# Raw Capture
|
|
|
|
This tool captures keyboard input from /dev/input/eventX and pipes it to the fifo accordingly.
|
|
|
|
It is meant to be ran from it's own tty, and is not meant to be used with a graphical environment, although a full screen terminal emulator will work for most input.
|
|
|
|
An escape sequence of escape+f1 will exit the program, but this can be changed via a command line argument.
|
|
|
|
|
|
## Why
|
|
|
|
This mode is especially useful for workflows with a lot of keyboard shortcuts or use of modifier keys, for example i3wm.
|
|
|
|
Generally a user would be in this mode when not typing extensively.
|
|
