Some functional keys are not passed to the guest systems about v86 HOT 9 CLOSED

ALT+TAB cannot be captured by the browser. F5 can be captured, but is currently intentionally ignored – I didn't want to break browser functionality too much. I'll add a button for ALT+TAB and F5. And try to fix the WIN key.

I would sincerely suggest that you rethink your approach regarding F5, and consider capturing it after all. For the last 10 years I have worked in several enterprise web software companies (for living, not related to KolibriOS), and ALL OF THEM have disabled F5 in browser while their software is used, since it would be very embarrassing to any user to fill some complex web form, and then get all his/her work lost due to pressing F5 by mistake. It happened to myself a few times even, and it was VERY annoying, to say the least.

I'll send F5 to the emulator and block page refresh for now, unless someone complains.

Thank you very much - I really appreciate that! I don't think many people will complain, since they always can use "Reset" button which essentially does the same as pressing F5.

I have tested your changes right now on your website:

• Disabling F5 key works great (behaves as expected)
• WIN key now opens the "Start Menu" in the emulator, but it still opens the "Start Menu" in the host system (Windows) at the same time. So unfortunately it's still unusable (as host system "Start Menu" hides the emulator screen).
• ALT+TAB works strange. It seems that pressing "Send ALT+TAB" button only sends the button press, but doesn't send button release. So the emulator thinks that ALT+TAB combination was never released.

from v86.

It doesn't seem to be possible to block the Start Menu in Windows – there's nothing I can do (except adding another button for it).

A release code is sent for alt-tab. Possibly there needs to be a delay between the keydown and keyup.

Regarding ALT+TAB - I have 0 knowledge in JS, but I have taken a look at your code:
ps2.kbd_send_code(0x38); // alt
ps2.kbd_send_code(0x0F); // tab
ps2.kbd_send_code(0x38 | 0x80);
ps2.kbd_send_code(0x0F | 0x80);

There could be a few reasons why that code doesn't work:

1. You send 2 scancodes (one for ALT, second for TAB). Some websites (although not all) mention that ALT+TAB pressed together has a single special scancode (different from scancodes for ALT or TAB pressed separately): 0xA5: http://www.freepascal.org/docs-html/rtl/keyboard/kbdscancode.html
2. If websites mentioned in (1) are wrong, then the order for key_up should be reversed: first release TAB and then release ALT (like you do yourself when you work).

from v86.

The link in (1) is a different kind of scancode, I guess used in Pascal. For the record, PS2 scancodes can be found here: http://stanislavs.org/helppc/make_codes.html

(2) is makes sense, I'll change it to work that way.

I have retested ALT+TAB again in KolibriOS, and it's working fine now, thank you!
