Get Keypress
Listen for a keypress, then apply keypress to a function or echo it to the terminal screen. The user must be in a terminal to use getkp; it will not work in RStudio or the R GUI. All actions within R are halted until the keypress is returned.
getkp(fn = list(), echo = FALSE)
fn |
list of named functions |
echo |
whether the keypress should be echoed to the screen if not found in list |
character naming the key that was pressed (invisibly).

'left' = function(){mv(col=-1)},
'right' = function(){mv(col=1)}
)
