Keyboard shortcut for Increase Font Size not working and incorrect shortcut shown in the Edit menu

[AlfGit]

Edit menu shows Increase Font Size shortcut as 'Ctrl+ Unknown KeyCode: 0x2b'. The same behavior is seen on W10 and W7, with Logitech USB (HID keyboard device) and Microsoft PS/2 (standard PS/2 keyboard) keyboards.

Fair enough, although I think one is a consequence of the other. It appears that KeyStroke.getKeyStroke does not like '+' as an argument. To clarify, it is not only displayed incorrectly, but the shortcut Ctrl+ Plus does not work.

Sorry, I misunderstood the issue report because you only talked about the menu issue in the description and I tested that the new keyboard shortcut Ctrl+MouseWheel was working correctly. I forgot it is also Ctrl+Plus, though I should have noticed that Ctrl+Minus is Decrease Font Size. I've updated the title. Thanks for the issue report!

Thank you. That describes the issue perfectly.

I took a look at this issue and it seems quite complicated to solve.
In fact, on keyboards with english layout the + key is only reachable through a modifier, so it breaks the shortcut. A solution would be to use the + key on the NumPad but it doesn't exist either on most laptops keyboards. If we switch to = which is primary on en keyboards we lose the integration for a lot of other locales...
I'll think about it and report back if I find something interesting/feasible.

The + and - on the numpad are already assigned to opening and folding code blocks, which I would say is far more useful because it's a function that would likely be used repeatedly. I imagine that most people would set their preferred font size once and then leave it, and there is still Ctrl+ mousewheel for those of us that use zoom more often. Of course, not all users have mousewheel functionality either, especially those using a trackpad on a laptop.
