[TxMt] Looking for the equivalents to some Emacs commands

An approach here is to record a Macro. Search and Replace the Regular  
Expression “(?<=\S)\s{2,}” with a single space (using the Previous  
Button, that is searching backwards). The Problem of this is that it  
will not match the current whitespace thingy when you are directly at  
the start of it. A pragmatic solution to this is to press `⌃F`  
before searching, and so moving the cursor one column to the right.  
Of course one could also do it with a Command and make use of  
`TM_INPUT_START_COLUMN` (see recent release notes of “Cutting  
Edge” Build 1200) to get the current caret position and start  
searching from there.

I haven't used emacs for quite some time now, but I remember using  
that command a lot as well, when TeXing. I think there might be some  
people interested to see this working for LaTeX so you might get help  
there. So this builtin Command would have to be overridden for  
specific Bundles (or all bundles depending on the Text Bundle) and  
could implement the logic needed.

There was some discussion about Soft Wrap indentation already. I  
think it is on the TODO List but you should not count on it to be  
implemented too soon.
But generally, I don't understand why one would not want to insert a  
hard line break and some more whitespace in that case. HTML does not  
care about that whitespace at all (if it's not inside a preformatted  
block). When someone else looks at the source with a different Wrap  
Column Setting all he will see is little mess ;) But that's personal  
preference for you.


Have a nice day,
