Is there a keyboard shortcut in OpenOffice Writer that will allow me to incrementally change the font size?

If I'm switching between 12 and 14 and 16 often, it would be much easier to be able to tap Ctrl + a a of couple times to go from 12 to 14. The function I'm looking for would be similar to Firefox's zoom feature.

not programming related. Anyway, go tools->customize->keyboard, there you can associate shortcuts to various functions. – Nick Dandoulakis Aug 23 '09 at 18:36

Go to Tools -> Customize -> Keyboard.

Choose "Format" from the column on bottom-left called "Category".

Choose "Increase Font" & "Reduce Font" from the bottom-middle column called "Function".

(Note that Ctrl++ is broken; you can't use the normal keyboard plus, you need to use the numpad plus, or another keyboard shortcut.)

Althought not by default, you can assign a keyboard shortcut to this function.

Go to Tools Menu -> Customize -> Keyboard

And? What is next? Why do you answer only one half of the question? – Val May 25 '13 at 11:17

CTRL + [ and CTRL + ].

This does not work for me. Perhaps because OpenOffice writer politically does not have the functionality to increment/decrement the sizes, I wonder how you manage your hotkeys to call non-existing functionality. – Val May 25 '13 at 11:17

"IN THEORY" you can create custom keyboard shortcuts as suggested above, but they don't work, certainly not like MS-Word. (a number of reasons have been suggested as to why, but that's irrelevant)
HOWEVER, you can customize the FORMATTING TOOLBAR, and put the Increase/Reduce Font Size buttons on the toolbar, which is what I do in Excel
(View -> Toolbars-> Customize: and those two buttons are not selected by default)
For me, this is now working like it does in MS Office

A quicker way to achieve this: click the dropdown caret to the right of the menu, and go to Visible Buttons -> Increase Font or whichever you want to add to the toolbar. You can also remove this way. – Tricks for the Web Feb 2 at 0:12
