This is a extremely simple addon that shows and on screen keyboard to send a chat message to your current group only, or on /say if you have no group.
There are no settings but if you need to change the scale or the keyboard characters you can edit the .lua file and change the first few lines I will improve it with some form of settings in the future.
Currently needed for my SteamDeck, because invoking the system keyboard sometimes reboots the device.
The keyboard is only for the chat, it cannot be used for group finder, macros or anywhere else - Only chat!
To use the keyboard, create a macro with the command /tscb , so you can press the button on screen (Or bind it to some physical key)
