Taking screenshots on a Mac changes letter function

Presumably it seems to make every letter perform functions that would usually be activated by holding down "control" or "command" on a MacBook

A - Deletes all previous text

C - Cuts or Removes text (I know it removes at least)

V - Pastes text

B (outside of chat) - Turns on Narrator

Steps to reproduce

1. Take a picture with command + shift + 4 on a MacBook (Player must stay shifting afterwards)
2. Take a picture the same way but unshift
3. Tap the letter b or try writing any of the letters above it in chat after a message

Expected Results: It would work as usual afterwards

Actual Results: It seems to automate the command button on the Mac in chat and control button outside of chat
