The strikethrough text formatting button in the group chat text box has the keyboard shortcut "ctrl+shift+x" which currently conflicts with a seemingly built-in shortcut to flip the orientation of the screen from left-to-right to right-to-left, flipping the user sidebar from the right side to the left side in the process, so the strikethrough keyboard shortcut is functionally useless at this time.
