When using different Keyboard shortcut for every window, keyboard shortcut doesn't work when we switch between applications
CTRL, ALT, Shift, tab are fine, but all of the characters are no response, such as G, E, Shift D, etc.

Exact steps for others to reproduce the error

switch applications in between blender and others.

Does that mean this happens after switching to a window that belongs to another application then coming back to the Blender window?
Does this happen with a particular application or any application even the ones installed with Windows?

Yes, it happen after I click and jump to other application such as whatsapp, chorme, ..... no difference what application it is, then go back to blender ; all the characters are no response but , . ; ' also fine. It is not only affect the shortcuts, I can't type anything to rename a material too.

I'm not sure what are the steps to reproduce the problem.

Are you sure that the Blender window is activated when you type the keyboard keys.
Keyboard shortcuts always go to the activated window, (not the one the mouse cursor is over).
To activate a window, just click on it.

Inside blender the situation is different, the shortcuts only work if the cursor is over a region.
For example, if you type G with the cursor over the outliner, the object selected in the 3D View will not move. To move it, press G with the mouse cursor over the 3D View.

Does what I said make sense to you?

I apologist for my English first.

I am glad for your patience to explain how to work with blender correctly. I can tell, I understand about the basic control in blender well.

Answer your question, I am pretty sure the keyboard is work in blender, because I can press Ctrl+S to save file well or everything goes back to normal after I quit and reopen the file again.

I just found another occasion, the problem comes out again after I switched from layout tap to shading tap. Same same, G is no response but I can see the index shows up on bottom left when I press shift, ctrl, alt.

Thanks

Hi, do you have multi-monitor setup?
Very often I switch between multiple applications and I've never seen this issue
It'll help if you find the exact conditions when this issue occurs.
Can you check again with factory settings?: {nav File > Defaults > Load Factory Settings}
Maybe related?: #97121 (still no evidence that #97121 is a mac specific problem)

Hi, actually I am using a laptop without any monitor.

I found that the most frequently situation is that I switch to other application for a while, such as whatsapp, brave, chrome.... and go back.

Even I had tried factory setting / uninstall blender, there's nothing change.

I have the same problem too, I've just installed version 3.3, and I have 2 monitors (one of them is a tablet).
I cannot use any of the hotkeys after I switched from Blender to other windows (chrome, discord etc)
Because I'm new to this software, I need to switch bewteen blender and chrome to watch tutorials.
It is nearly unable to use blender like this, please help ;_;

Hi there,
I have found a way to fix it. In my case, i use 2 in-build windows keyboard layout (Eng and Vietnamese) and the blender will be freeze after couple of alt+tab. There are 2 way i use to fix this issue:

I set my in-build keyboard to sperarte for each windows and when the blender freeze, i change it to my alt keyboard layout (mine is vietnamese keyboard).
I remove all of my language / in-built keyboard layout and leave it in single windows OS language. This issue never happen again.

Hope it can help you well,
Tam Huynh.

I also have this exact problem but with Chinese keyboard, and your solution works for me, but the problem with my alt Chinese keyboard is that wherever I press any shortcut key with “shift” in it, it will type Chinese which is a super annoying workaround.

Dear Rizum,

Unfortunate, there are only one way to fix that, you should remove all keyboard and use only English Layout.

You can disable, *Let me use a different input method for each app windows over Time & Language -Typing-Advance keyboard settings.
That's the main reason the bug appears.

I also have this issue with my Win 11 laptop (connected with extra monitor, keyboard layout per application).

I hve two physical keyboards: modified Chinese (Simplified) - US Layout (based on KLID 00010402 (bg) arrangement ANSI104) which comes with laptop and United Kingdom Layout (KLID 00000809 (en-GB) arrangement ISO 105), and three keyboard layouts (chinese simplified, chinese traditional, english uk)

if I change keyboard layout just before tab out from blender then change back after tab back in, that seems to be all good. Although remember to do this evey time is just annoying :c

Device currently on 22H2 22621.2361 (with Windows Feature Experience Pack 1000.22674.1000.0), drivers all up-to-date.

I may be able to suggest a dirty way of handling this problem... Just put system->handleKeyboardChange(); in WM_SYSCOMMAND, WM_PAINT and WM_DPICHANGED, that would probably ensure the correct keyboard layout after the user returns the program.

But there's another issue that's with the Alt key. (I don't think it's always on windows, I have some problem with this on linux too I believe, might also be one of other programs I wrote myself), because when you alt-tab, the program is switched without it knowing that the alt being released. So when you go back, sometimes blender will persist that alt state? But every time if the keys don't work I just press ctrl alt shift once and apparently it solves the issue...
