I recently discovered that the Mac has a lovely tendency to treat the Home and End keys on a 105-key keyboard as instructions to go to the start or end of the entire file, respectively.
I did some searching across Stack Exchange a while ago and found some tips that helped (sorry can't remember what they were now). Some applications now behave sensibly.
BUT when using Aptana Studio 3 these keys still persistently jump to the start or end of file. Since I've been using these keys for decades to go to the start or the end of the line, I press them a lot and then proceed to swear loudly.
I'd love a system-wide fix that works consistently but I'll be happy if anyone can point me to a fix for Aptana as that's where it hurts the most.
