OK, I am sure everyone knows this already, but it was news to me.
When working, I am often right-clicking, scrolling to a menu option then left clicking to activate the option highlighted.
I just noticed that I can right-click to select the menu, scroll down – then right-click AGAIN to select it.
I tend to get RSI at times, and most of it is mouse generated, expecially when I am doing a lot of left clicking.
This should reduce my left-clicks by about 10% and help alleviate any RSI attacks.
For the record, I have tested this in MSie6, Firefox 2 and several MS Office applications – all running on Windows.
