I know modern software is driven by graphical user interfaces, but as an old-school Unix admin (there were loads of interface choices – Bourne shell, c shell, korn shell, bash shell!) it’s weird to take my hand away from my keyboard just to turn a bit of text bold or move to a new field. And Microsoft has done a decent job of standardizing keyboard shortcuts across their applications – ctrl-b will toggle “bold” pretty much anywhere (even Teams!)
But … within your Teams client (even the web client) hold the “Ctrl” key and type a full stop (.) and look – special keyboard shortcuts!
There’s even a link at the bottom for all of the shortcuts on Windows and Mac. I can hit ctrl-shift-1 to flip over to my Activity feed; ctrl-shift-3 puts me back in the Teams chat section.
