Adding custom lists to Excel and OpenOffice.org

In the last post I demonstrated how to easily enter lists of numbers, days of the week and months of the year in Excel and Calc (the OpenOffice.org spreadsheet application). Both programs offer the option to add custom lists to this feature. In this post I will show you how to add the colours of the spectrum as a new list.

Excel 2003 and earlier
Open up Excel and type the colours of the rainbow into one of the columns, then select the cells as shown below.


Pull down the 'Tools' menu and select 'Options', then go to the 'Custom Lists' tab.

You should see an entry in the 'Import list from cells' box. Click on the 'Import' button to the right of this to add the list.


The colours list will appear in the 'List entries' box. Rather than type the entries into cells, you could just type the list in this box, pressing Enter after each item, and then click the 'Add' button to save the list.

Click 'OK', and the list is available to use. Simply type 'Red' in a cell and drag the handler down to automatically fill consecutive cells with the other colours.


Excel 2007 and later
Follow the previous instructions, except to open the 'Options' box click the Microsoft Office Button (shown right), and then click the 'Excel Options' button.

On the 'Popular' page, click the 'Edit Custom Lists' button and continue as above.


OpenOffice.org Calc

Type the list of colours into a column of cells and select them as shown.



From the 'Tools' menu, select 'Options', then click the + next to 'OpenOffice.org calc' in the list, to expand its entries, then click on 'Sort Lists', as shown.

You should see an entry in the 'Copy list from' box. Click on the 'Copy' button to the right of this to add the list.

Click 'OK', and the list is available to use.

As with Excel, you can enter a list manually by clicking the 'New' button on the 'Sort Lists' option box, typing in the entries, and then pressing the 'Add' button.

How to quickly enter lists in Excel and OpenOffice

Excel spreadsheets often have a column or a row of incremental data. That is, information in the form of a list of numbers (1, 2, 3, 4, etc), times (09:00, 10:00, 11:00, etc), the names of months or the days of the week. You could type all this information into the row or column yourself, or you can let Excel handle it for you.

To try this out open Excel and type 1 in any cell, and 2 in the cell below it. For lists of numbers you need to enter a couple of numbers so that Excel knows where to begin and what interval to use.

Select both the cells (by hovering the mouse pointer over the top of one, holding down the left button, moving to the other cell and letting go).

You will notice that there is a small square in the bottom right hand corner of the selection box. If you hover the mouse pointer over this square the pointer will change to a + symbol. If you hold down the left mouse button and drag downwards Excel will fill in the cells continuing the series of numbers.

You can do the same with larger increments too. The images to the left show the same process being used to generate is a list of numbers with an interval of 10.

But that is far from all you can do with this process. You can drag these lists in any direction so that you can create rows as well as columns. Also, you are not limited to numbers; you can produce lists of months, days of the week, and times. I have included a video in this post showing this feature of Excel in action creating a few of these lists.

Calc, the OpenOffice spreadsheet package, works in pretty much the same way, except that there are no default intervals for times. So, if you enter 00:00 and drag the handler down selecting consecutive cells they will all also be filled with 00:00, but this is easily solved by entering 00:00 in the first cell and 01:00 in the second, then selecting both cells and dragging the handler down.

In the next post I will show you how to set up your own custom lists in Excel and Calc.

Can't save an image on a web page?

A number of websites are set up in such a way that you cannot save imagesthat they include. Some of these include scripts to disable right-clicking, meaning that you can't bring up the pop-up menu that includes 'Save Image As...'. There are a variety of ways of getting round this, such as disabling JavaScript on your web browser. Other sites are set up in such a way that images are layered, making it difficult to select the right image to save. One solution that works in both cases is to save the entire web page and then delete all the files that you don't need. Firefox offers a simpler alternative: the 'Page Info' window.

When you right-click on a website you will see an entry on the pop-up menu that reads 'View Page Info', which you can click on to open the 'Page Info' window. This window has a number of tabs, including one called 'Media' shown below. If you go to that tab, you will see a list of all the images on the page and a 'Save as...' button that you can use to save any image from the page.

OpenOffice Keyboard Shortcuts

Writer, the word processor in OpenOffice.org, uses many of the same keyboard shortcuts as MS Word. The shortcuts for selecting, editing and formatting text follow established standards. Whereas Writer has a keyboard shortcut for 'Paste special' (Ctrl + Shift + V) - something missing in Word - it does not have one for changing the case of selected text. It is possible to set up new shortcuts in Writer, and I will show you how to set up one to make the selected text upper-case and another to make it lower-case.

In Writer pull down the 'Tools' menu and click 'Customise'.

Select the 'Keyboard' tab, as shown below.

You can see all the default keyboard shortcuts, and some spare key combinations.

I have chosen Ctrl + Shift + U to make selected text upper case, and Ctrl + Shift + L to make it lower case.


Find Ctrl + Shift + U in the 'Shortcut keys' list. Select 'Format' from the 'Category' list, and then 'Uppercase' from the 'Function' list. Click the 'Modify' button to make the change.


Repeat the process selecting Ctrl + Shift + L, the 'Format' category, and the 'Lowercase' function, not forgetting to click the 'Modify' and then the 'OK' buttons when you are done.

Open new tabs on the right in Firefox 3.6

Mozilla have changed the way that new tabs operate in Firefox 3.6. When opening a new tab from a link on a web-page, the new version of Firefox will place it to the right of the current tab, rather than at the far right of the list as it did in previous versions.

To revert to the old functionality type about:config in the address bar and then click the "I'll be careful, I promise!" button if it appears.

In the filter type tabs.insertRelatedAfterCurrent and then right-click on the entry and click "Toggle".

Linux Applications: Part 3 - Web Browsers

There are many different web browsers available for Linux. These include Firefox and Opera, but not Safari nor Internet Explorer; however, a Linux version of Chromium (the open-source browser on which Google Chrome is based) is in the pipeline. A number of less well-known browsers are also available for Linux. In this post I will list a few of these.

Epiphany
This is the web browser for the Gnome desktop environment. It uses the WebKit layout engine, as used in Safari.






Flock
This browser specialises in social networking facilities and is based on Mozilla Firefox.



Konqueror
This browser also doubles up as the file manager of the K Desktop Environment (KDE). It uses the KHTML layout engine from which WebKit was developed.




Midori
This lightweight web browser also uses the WebKit engine. It is now part of the XFCE desktop environment project.




Swiftfox
Like Flock, this is based on Firefox and is my browser of choice. It is a lightweight browser optimised for various processors that supports Firefox extensions and plug-ins.

Linux applications: Part 2 - Music Players

In response to my last post listing Linux applications, I received a couple of comments asking whether there are any applications like iTunes for Linux. There are a number of applications that offer many of the features of Apple's music player. Here are a few of the most popular of them.

They all include roughly the same set of features such as support for audio file types and digital audio players, including the iPods. They retrieve album, submit played track information to Last.fm, and supports podcasts. With such software, look and feel are all important, so I have included screenshots and links to the homepages of each. Since they are all free why not audition them all and find the one that best suits your requirements.















Personally, I prefer a more svelte audio player like Winamp. Since there is no native Linux version of that, I use Audacious, which supports some Winamp skins. That is probably just as well because the default skins are not great.


More Linux applications soon.
