This works for me (TMHO, this demonstrates the beauty of LC).
Script your field with the following.
on rawkeyDown k
case 32 -- space
put numToCodePoint(0x00B7)&numToCodePoint(0x200A) into the selection
case 65293 -- return
put numToCodePoint(0x23CE)&cr into the selection
case 65289 -- tab
-- put tab&numToCodePoint(0x21E5) into the selection -- alternate
put numToCodePoint(0x21E5)&tab into the selection
For converting the whole field *or a visible part of it* (you could use a check button)
use the replace-script of my last post. For a few lines (< 500), put into a temporary
field, conversion preserving styles is still fast.
