I'm a sucker for anything that saves me time when using my computer, which isn't entirely surprising considering how many hours a day I spend in front of a PC. As a result the smallest innovation can save me a considerable amount of time over the course of the day. A while ago I wrote my love of keyboard shortcuts and I would now like to introduce mouse gestures.

Popularized by the Opera browser, the mouse gesture is slowly but surely gaining support from both software developers and users. The idea is that rather than having to click on an icon or use a keyboard shortcut, the user instead holds down a mouse button (usually the right) then moves the mouse in a certain gesture (for example from right to left) and then released the button. This gesture is then converted in to relevant command, for example the commend 'go back' in a browser window. Whilst still not big in personal computing, gestures are already very popular on devices such as a PDA's (Personal Digital Assistants) as the omission of a keyboard means that conventional keyboard shortcuts aren't available as an alternative to laboriously clicking icons.

As an example of how mouse gestures could be used, let's take a look at a few of those already built in to the Opera browser. All of these gestures require you to hold down the right mouse button and then make the movement indicated:

Previous Page - Move mouse left

Next Page - Move mouse right

Home Page - Double click right mouse button

Open New Document - Move down

Reload Page - Move up, then down

Maximise Window - Move up, then right

Minimise Window - Move down, then left

Close Document - Move down, then right

Opera has had mouse gesture support since way back in 2001 and unfortunately as of yet neither Firefox nor Internet Explorer include support straight out the box. Both applications can be upgraded through with the use of add-in applications; those using Firefox should head to http://optimoz.mozdev.org and for Internet Explorer check out www.ysgyfarnog.co.uk. Of course, both these utilities are very small downloads, completely free and don't include any advertising.

Support and usefulness outside of the humble Internet Browser is not hugely widespread, the majority of applications don't require shortcuts for repetitive commands so mouse gestures aren't always applicable. However I would be delighted to see Operating Systems take up support of mouse gestures and I'm shocked that Vista didn't capitalise of this emerging innovation.

I will also admit that I think the potential number of commands that can be accessed in this fashion is limited but once you've got used to using mouse gestures, it's undeniable that they can reduce the amount of time taken performing repetitive tasks.
