A warm welcome
from the dark side
Falps!
To help you along a little, many of the basic keystrokes are actually the same on a Mac as in WinBlows, except that you should use the 'Cmd' (Command) key (also known as the 'Apple key - the one with the Apple logo, to right and left of the spacebar), instead of Ctrl.
Thus, Copy is Cmd-C, Paste Cmd-V and so on. Cmd-W closes windows, Cmd-O opens them. The Command key also invokes the right-click function if you're using a one-button mouse with the lappy.
Once you get used to those basic differences, you should be on your way! You're more than welcome to PM me if you need help with anything specific
