Colloquy is definitely the way to go, as previously mentioned
Yeah, getting used to using Function-Delete to do the good-ol delete is taking some getting used to.
I use “home” and “end” a LOT and now that I don’t have them on my MBP keyboard I have to get used to using command-left-arrow and command-right-arrow
That is my biggest gripe… I refuse to use an external keyboard because then I won’t be able to do anything on this one when I’m in an airport or on the road, etc…
At work, I use a G5 with a Microsoft wireless keyboard (slow cannibals end up with Dell keyboards). Apparently, I thought it would be a good idea to swap whatever the two bottom left keys are when I first started working there, so now I have bunches of fun switching from OSX there, to OSX with an Apple keyboard, to Linux, and even to Windows now and then. App launcher in Linux uses Super (Windows) + Space. In OSX it takes “Control” + Space. In Windows, it’s Alt + Space. At work, I use Photoshop and at home I use GIMP… yeah, keyboard shortcuts sometimes have very unexpected results when I mix them up!
