[Qt-creator] Editor Keybindings & Signature Tool Tip

[Sebastian Fischer]

Hello again,

I    have    found    a    few    issues    with    the   keybindings:
'TextEditor.DeleteLine', which I prefer mapped to Ctrl-D, doesn't seem
to  be saved and has to be changed again after every Qt Creator start.
This  applies  to  all possible bindings for the TextEditor.* category
(with the exception of .CompleteThis, but see below).
This might be related to: The entire TextEditor.* category (again with
the  exception  of  .CompleteThis)  is absent in the options until any
file is opened in the TextEditor.

Also a few questions/suggestions about the signature tooltip:
There doesn't seem to be a way to get the function signature help
back that helps one filling out a function parameters by highlighting
the  current parameter from the definition in bold (so you know what
to pass as argument). It's usualy shown after a function's name was
completed, the opening parenthesis typed (or auto completed) and a
signature selected from the showing list.
Why, if there is only one signature why do I need to select one
from a 'list'? Obviously the only one existing is the one I want ;)
But most importantly, could/will there be a keybinding to specifically
request the showing of that tooltip? The only way I've found is by
using Ctrl+Space with the cursor right after the opening parenthesis.
If it's further into the arguments (even just one space) I only get
the auto completion drop-down for all available 'things'. I often
would like it back after I've had to scroll to look up a variable name
or something (which hides the tooltip even without cursor movement).
How about Ctrl+Shift+Space (like in Visual Studio) as a default?

Qt Creator 0.9 (build 320645), WinXP.

PS: I've already sent this to the list 8 or 9 hours ago, but it seems
it never made it, no idea why...
