[LibreOffice] find ctrl-g/ctrl-shift-g accelerator patch

[Jan Holesovsky]

Hi Cameron,

This is some good research, I hope you don't mind if I CC: the devel
mailing list, and the UX advise list too? :-)

Yes, this is not ideal.

I think this is actually a good question for the UX advise list :-)  My
proposal would be to get rid of the RepeatSearch functionality (and
consequently of Ctrl-Shift-f), and let only DownSearch and UpSearch -
more consistency, and more control for the user.  RepeatSearch it is not
accessible from the menu, so I'd expect that not that many people will
know that - but of course some hard data would be good here.

So - if the UX advise guys agree, I'd try to make DownSearch and
UpSearch working even without the toolbar active.  The code for
RepeatSearch is here:

sw/source/ui/uiview/viewsrch.cxx

The code for Up/DownSearch here:

svx/source/tbxctrls/tbunosearchcontrollers.cxx
[DownSearchToolboxController::execute()]

I'd try to look if the control flow gets to the ::execute() when you
bind Ctrl-g to .uno:DownSearch and use it in the document.  If yes, then
it might be only a matter of checking why exactly it does nothing.  Of
course, if the control flow does not get there at all, it is for deeper
investigation - I'd then try to spot differences between what is
happening in the .uno:RepeatSearch and .uno:DownSearch case.  If it gets
more complicated, please let me know; but hopefully it'll be OK.

Good point!  I have just checked, and it is a more general problem -
when you try that in eg. the 'Font size' combobox, you cannot do Ctrl-s
either.  Should I file an easy hack for that, or will you try to
investigate this one too? :-)

All the best,
