Keyboard → Switch Layout shortcut conflicts with Alt+Tab #4

Open cassidyjames opened 6 years ago

cassidyjames commented 6 years ago

Our default "Switch layout" shortcut for switching between keyboard layouts is Alt+Shift, but that conflicts with and breaks Shift+Alt+Tab to switch windows backwards. We should disable or change this shortcut since we keep getting bugs about Shift+Alt+Tab being "broken".

Moved from https://github.com/elementary/gala/issues/18

I really recommend to change the shortcut as working in different languages gets much more convenient with a shortcut.

Philosoft commented 6 years ago

This is a big problem indeed, but "change one of conflicting shortcuts" is not an option - it's just avoiding and postproning general problem. If change layout is bind to alt+shift, then it brokes every other shortcut wich starts with alt+shift, if you change it to something else, some other shortcuts will be broken. why windows, mac, gnome, kde etc can solve this problem and elementery can't?

Also on topic. alt+shift, alt+tab, alt+shift+tab is common across desktops and countries, why change defaults?

Most of all, why can't I map my own shortcut to switch layouts?

lewisgoddard commented 6 years ago

I assume this a problem somewhere where the shortcuts are detected and passed off. Maybe we are detecting alt+shift on keydown instead of keyup?

davidmhewitt commented 6 years ago

This is a very long standing issue in X itself, GNOME is almost certainly affected too.

I think our only option really is to bind the language switching shortcut to something that doesn't conflict. Which is easier said than done, since you could move it to Ctrl+Shift, but then Ctrl+Shift+Tab would stop working for switching tabs in a web browser. But a slightly less common conflict than Alt+Shift+Tab I would guess

lewisgoddard commented 6 years ago

Why not something that doesn't conflict at all, like Ctrl+Alt+L?

Philosoft commented 6 years ago

@lewisgoddard i, myself, would prefer AltGr to do so, but there are not any suitable options (or as you propose custom ctrl+alt+L. screenshot:

as I additionaly notice, you just cannot screenshot popup menu with PrtSc - it simply doesn't work.

danirabbit commented 6 years ago

I'm going to bump this to beta2 since it doesn't imply any string or UI changes

danirabbit commented 6 years ago

I'm going to drop this from beta2 since it seems discussion is still ongoing and an agreement hasn't yet been reached

peteruithoven commented 5 years ago

How did other Distro's fix this?

@danrabbit @cassidyjames Maybe one of you (being the most public) could do a poll on Twitter and/or Reddit?

janxkoci commented 5 years ago

FYI: Gnome switches language input with Super+Space (and this cannot be changed btw). Alt+Shift is familiar to all my Windows colleagues.

And to @Philosoft - most desktops I used in recent years cannot take screenshots with open popup menus with simple PrtSc press - I always had to set a timer for such screenshots. What I'm saying is that this is by far not unique to elementary.

cassidyjames commented 4 years ago

Windows uses Alt+Shift, but as @davidmhewitt it seems problematic to bind it to only modifier keys that are used in other shortcuts out of the box. GNOME uses Super+Space which we use for Applications Menu. It looks like macOS uses Ctrl+Space/Alt+Ctrl+Space to cycle in different directions: https://support.apple.com/guide/mac-help/type-language-mac-input-sources-mchlp1406/mac

I'm going to propose we change the default key in elementary OS to not conflict with the Alt+Tab switcher. Any combination of only modifier keys (e.g. Alt, Ctrl, Shift, and Super) seems to be a bad idea as it will inevitably conflict with shortcuts in the system or in apps. Thus, Alt+Space seems like a sane option (which already exists in the options), or if possible, Ctrl+Space to at least match one other platform (macOS).

And remember, users can always change it to something that is more familiar/comfortable for them in System Settings → Keyboard.

tom-james-watson commented 4 years ago

Sounds like a sane change. I think Alt+Space is a good choice, personally.

janxkoci commented 4 years ago

I agree with alt+space, as ctrl+space is very popular with 3rd party launchers like Synapse, Kupfer, GNOME Do, and others (and I think some don't allow to change the combo).

tom-james-watson commented 2 years ago

I've not tried it but from some blog posts I read, it sounds like this issue has been fixed and that alt+shift+tab should now work?

cmonagle commented 2 years ago

Is there an update on this? It looks like @cassidyjames was proposing Alt+Space. Would a PR be welcome to implement this? As far as I can tell it should be a few lines in this repo? If that's the case I'm happy to open one (but if it's much more than that I'm afraid I may need help or to pass it off).
