Re: [Orgmode] RFC: interactive tag query adjustment

[Christopher League]

Hi again, last month I proposed an idea for interactively manipulating  
the current query in a tags agenda match (C-c a m, org-tags-view).   
Attached here is a patch against 5.18a that implements this idea.   
It's pretty slick, if I may be so bold!

In a tags match buffer, the prompt will now say, for example:

Headlines with TAGS match: office
Press `C-u r' to enter new search string; use `/;\=' to adjust  
interactively

The extra keys are / (and), ; (or), \ (not), = (clear).  Any one of  
them will bring up another window, much like fast tag selection.  You  
can press one key to select the tag or TODO keyword, and that will be  
added to or removed from the query string accordingly.

So, starting with the query "office", I can hit the keys ";p/N-f" to  
transform it to "office|phone-focus/NEXT", assuming my tags and TODO  
keywords are assigned those keys already.  Like fast tag selection, it  
supports single-key (the default), multi-key (waits for RET), and  
expert (no separate window) modes.

Enjoy.. comments & critiques welcome.

CAVEATS:

1. Carsten, my signed papers are on their way back to FSF; I'll let  
you know when I have a copy with their signature too.

2. Keys (even auto-assigned ones) can conflict between the tags and  
todo-keywords; in this case, the todo takes precedence.  This is  
disappointing if you have a key assigned to tag "focus(f)" and  
meanwhile have a "#+TYP_TODO: Fred" in some buffer.  Fred will get  
assigned the key "f" and make "focus" inaccessible.  Same thing  
happens with fast-tag-selection if include-todo is on, so it's not  
unique to my patch, and maybe needs a more general solution.

3. The main function `org-agenda-query-selection' started as a copy of  
`org-fast-tag-selection' and there are possibly some parts that could  
be reasonably factored out of both and shared.  (Mostly the code that  
lays out the tag names and keys in the buffer.)

4. ...? Let me know if you find anything else strange.
