Description:
Think this is a 'bug' 

At least it does not do what the user would expect:

LibreOffice Writer
Tools >
Customize >
Keyboard >
Category: View >

Set keys & Modify to:::

Zoom In = Ctrl++
Zoom Out = Ctrl--

Once modified in Keys, click OK

Nothing happens when using these keyboard shortcuts.

If you need anything else, just let me know.

Thanks ;-)

(..."Confirm that it really is a bug. Most of the time, a bug is something that makes the software behave in a way that a reasonable user would not want it to behave. This includes the software not doing what you want it to do")

Steps to Reproduce:
LibreOffice Writer
Tools >
Customize >
Keyboard >
Category: View >

Set keys & Modify to:::

Zoom In = Ctrl++
Zoom Out = Ctrl--

Once modified in Keys, click OK

Nothing happens when using these keyboard shortcuts.

Actual Results:  
Nothing happens when using keyboard shortcuts

Expected Results:
Zoom in, and out (common keys Ctrl++, Ctrl-- work on lots of programs / applications - LO Writer being one of the few that doesn't)


Reproducible: Always


User Profile Reset: No



Additional Info:
Not such an issue on a desktop (where a user would more often have a mouse with a scroll-wheel and can probably use Ctrl + scroll.

But on a laptop with a touchpad - not so convenient.

And, just not what I 'expect' after actually setting those in keyboard shortcuts etc.
