bash - conemu macros 'line send delay' method? -

i use securecrt , it's 'line send delay' option. lets inject delay in milliseconds lines sent via mapped keys. helpful because mapped keys send commands fast os. ex:

command1\ncommand2\n 

needs entered as:

$command1 $command2 

not:

$command1 command2 $ 

from i've learned conemu's macros pretty similar securecrt's mapped keys. but, have not figured out "line send delay" option. else know how this?

print("command1\n"); sleep(1000); print("command2\n")
