Shortcuts interfere with OSX bound shortcuts
The Alt-E button in The Netherlands is standard bound to a "´" symbol, therefor in a message-inputfield you can't use that button to jump to the "find person/team" field because it will then type that character.
It really feels like no one at MS is using their app on a Mac. It's not possible to search if you are typing a message.
The same seems to be a problem with Teams Desktop (Electron) and Polish national letters on a PC/Win10. Whenever Teams is launched, I'm unable to produce ALT + a = ą, ALT + s = ś almost in any application (some are working but most of them - no). Others like ALT + (z,x,c,e,o) = (ż,ź,ć,ę,ó) are working. MS - come on - stop this madness!
Please stop using [ALT] as the only control key for shortcuts in Mac OS X, use the [CMD] key instead or in a combination with other control keys! [ALT] as the only base for a shortcut will ALWAYS be a bad in Mac OS X!
And please don't use special characters such as [/] in the combination, won't work form many keyboards where you have to press [Shift] to get the [/]...
BTW! Check your own products, such as MS Outlook 2016 for Mac which uses [CMD] + [1,2,3 etc]. Be consistent!
