Stop Ctrl+Click on messages from highlighting all text.
When working I often want to copy some text from a message in teams, and do so the same way I would elsewhere; by highlighting a section of the text in the message, and hitting Ctrl+C
I habitually have the ctrl key already held down when highlighting, or at least, have begun to press it just before letting go of left click. Teams reads this as a ctrl+click on the message and highlights all the message text, including the author and timestamp. The whole thing happens so quickly that I end up copying the entire message without realising.
Please either change the shortcut for highlighting an entire message, or have it not fire when letting go after a click and drag action.
