As a user of OSX on the mac since day one, a problem that a lot of newcomers to the system come across is the absence of a ‘minimise all’ feature. Windows actually solves this problem perfectly with the ‘show desktop’ button in the taskbar section. As far as I am aware there is no similar graphical way of performing this action in 10.4 but there is certainly a keyboard shortcut…
Option-Command-M
You could also set a Expose hotspot to do the same thing but personally, I have always found Expose a bit ‘gimmicky’. If anyone knows of a way to add a button into the doc to do this, be sure to let me know! Readers may also wish to take a list of other useful keyboard shortcuts for OSX, you can find them in the following Apple article… http://docs.info.apple.com/article.html?artnum=75459
