I want to port from Hypercard to Metacard a set of easy keyboard shortcuts to
move the cursor around and select text in a field. They require the left hand
to press combinations of shift, ctrl and option (note: I use a Mac) and the
right hand to press "H", "J","K","L",";" or "I".
Some scripts are working fine, but others aren't. For example, I cannot trap
ctrl-option-J. In fact, when I press ctrl-option-J, the text at the end of
the line that I'm on disappears and some hidden something-or-other(?) is
added to the end of the field. If I press ctrl-option-J or similar (ctrl-J,
shift-ctrl-J, shift-ctrl-option-j) over and over, the computer crashes.
My script is:
on controlkeydown what
put the shiftkey into s
put the optionkey into o
if what is in "HJKLI:;" then
case "J"
if s is down then
if o is down then
-- script to select text back a word
else
-- script to move cursor back a word
end if
else
if o is down then
-- script to select text back a character
else
-- script to move cursor back a character
end if
end if
break
case "K"
etc.
Any ideas what might be going wrong?
And if any intrepid souls want to test it: try pressing over and over a
random combination of: ctrl-j, ctrl-option-j, shift-ctrl-j,
shift-ctrl-option-j. Does your computer crash? Or is it just my computer? I'm
using OS9. It crashes when I'm running either version 2.4.3 or version 2.5A8.
Thanks.
