[TxMt] Selecting text until next found occurrence

[Shiran Pasternak]

How could I go use keystrokes to select text from the cursor to the  
next (or previous) occurrence of a searched term? This would be  
really helpful for automating tasks, for example, in quickly hacking  
out macros that can operate on variable-length text fields (where a  
"select until next tab" would be useful -- using ^W doesn't help with  
URLs). I'm aware that I can get around this using find-and-replace of  
an entire block of text via regular expressions, but was wondering if  
there's something more procedural.

Thanks,
Shiran
