[vim/vim] GVim 9.0 on Windows does not recognize the right Alt key (Issue #10826)

Steps to reproduce

Start GVim on Windows.
Type any Alt-key combination (other than a menu bar accelerator) using the right Alt key. For example, RightAlt-i works to demonstrate the problem.

Expected behaviour

If you hit RightAlt-i, Vim should invoke any mapping that exists for <m-i> or beep if no such mapping exists. Instead, it acts as if you simply typed i.

More detailed description of the problem:

GVim 9.0 on Windows does not recognize the right Alt key; if you hit RightAlt-Somekey, it acts as if you just hit Somekey alone.

The one exception to this is that the menu bar accelerators work: if you hit RightAlt-f, for example, it does invoke the File menu.

I'm using a US keyboard, so the right Alt key is not an AltGr key, in case that matters.

The left Alt key works fine.

Both Alt keys work in the text-mode version of Vim; only GVim is affected.

Both Alt keys work in GVim 8.2.

I've confirmed that the problem exists when starting GVim via gvim --clean so it's not a settings issue.

I've confirmed that the problem exists on two different computers, one running Windows 8.1 and one running Windows 10.

I've confirmed that the problem exists in the most recent stable version listed for download on vim.org (https://github.com/vim/vim-win32-installer/releases/download/v9.0.0000/gvim_9.0.0000_x86_signed.exe) and in a recent nightly (https://github.com/vim/vim-win32-installer/releases/download/v9.0.0117/gvim_9.0.0117_x64.exe).

Version of Vim

9.0 and 9.0.0117

Environment

Microsoft Windows 8.1 (64-bit) and Microsoft Windows 10 (64-bit)

Hello, this seems to be a duplicate of issue #10753.
@k-euser Could you try this build: https://github.com/vim/vim-win32-installer/releases/tag/v9.0.0124

I confirm that on windows vim9 x64 patch 0128, the command Ctrl+$ in a help file as vim9.txt help does not recognize goto command and don't bring me to definition of |vim9script|.

Nicolas.

That's not precisely a duplicate, although it might be related; #10753 is about AltGr-Space not working whereas this is about RightAlt-anything not working, on a keyboard layout where RightAlt is not AltGr.

In any case, I've just tried v9.0.0124 and the problem is still there.

Please reopen.

Recently tried to create test case for this bug using new test_gui_w32_sendevent low level key press simulation mechanism, but it fails: internally whatever key code i simulate gui_w32.c logic judges it as "left alt", thus performing all tests without revealing bug reported here. Only manually operating the keyboard i can reproduce the problem. Still have some hope, will try to extend logic in test_gui_w32_sendevent to use scan_code instead of wVk. Seems will not come to it very soon, have some busy weeks now.

It requires someone with this keyboard to figure out what happens and come up with a solution (that doesn't break things for other keyboards).

You don't need a physical keyboard with one of the affected layouts to reproduce the problem. You can reproduce it just fine using the "On-Screen Keyboard" included with Windows after setting the keyboard layout in Windows' Language settings.

(Actually, I suspect simply changing the keyboard layout would be sufficient to reproduce it on essentially any physical keyboard as well, but I don't have any way of checking that as I don't have a non-US keyboard available.)

No need any more ((( , just checked myself - it breaks AltGr handling completely (but US RightAlt starts to work though).
