ferdium-app: Bug: Hotkey CTRL+PLUS doesn't Zoom in on content

[tldr; this a problem coming from how electron interacts with Windows keyboard layouts.]

After a few tests on my Windows version, it appears that this is not consistent across different keyboard layouts: if I set the UK layout, then I have no problems whatsoever. However, other layouts such as French (windows or mac layouts) or Swiss (windows or mac layouts) give inconsistent results.

[I will use & to mean pressing keys jointly for clarity.] For example on the French one, the - sign is located on the same key as the number 6 but is the primary character (we need shift to use numbers), but typing ctrl & - acts instead as ctrl & 6 (change to 6th service). In the same way, ctrl & à acts as ctrl & 0 since à and 0 are on the same key. However, for the zoom in, + and = are on the same key with = the primary character, and there we do need to use shift (so doing ctrl & shift & = in order to act as ctrl & + as expected. On the other hand, for the Swiss keyboard, ctrl & - and ctrl & 0 works as expected (both are primary character of their respective keys), but the + is located on top of 1 and thus needs shift cannot be combined with the ctrl key as expected: ctrl & 1 does the change to the first service as expected while ctrl & shift & 1 which should act as ctrl & + does nothing.

Another thing interesting is that not all layouts are recognised appropriately: using the Mac layouts of languages fails when activating hotkeys and automatically uses the Windows layout, when it does work on other app (such as firefox which has the same hotkeys for zooming in and out). However typing into any text boxes is as expected with the correct layout selected. This problems doesn’t just concern us, I have tested on Discord which suffers of this (though they are soooo far behind on updating the electron they use, it might not be the best test example), so I am not sure if it is coming mainly from electron, or from Windows itself (built by default for US keyboard layout).

i can’t zoom in/out on Ubuntu 23.04 too and i don’t recall when it actually worked in past versions. The only zooming works from menu which is annoying.

Also extending this I am surprised that Zoom is not preserved when the service is reloaded or Ferdi is restarted. My services GChat, Slack, Zulip.

Same here:

Ctrl MouseWheel does not work

Ctrl - does work

Ctrl + does not work Ctrl Shift + does work instead

Thanks for the detailed info @Alphrag . I vote that we tag this as an upstream bug, which we can’t really fix. We can still keep it open for tracking purposes. wdyt?
