Apple - Can a Mac be programmed to simulate pressing a key at a certain rate via software?
I found a way to do this in a bash script:
#!/bin/sh
# Simulates hitting a key on OS X
# http://apple.stackexchange.com/a/63899/72339
echo "tell application \"System Events\" to keystroke \"$1\"" | osascript
Save as hitkey
, chmod +x hitkey
, hitkey k
to hit K.
From there it's simple to use Automator to loop over the script several times or make an iCal alarm to initiate the script at a specific time.
Here's an AppleScript to do what you want:
set i to 0
repeat while i < 15
set i to i + 1
delay 5
tell application "System Events" to keystroke "k"
end repeat
You can inline it in a shell script like this:
echo "set i to 0
repeat while i < 15
set i to i + 1
delay 5
tell application \"System Events\" to keystroke \"k\"
end repeat" | osascript
(Thanks to @houbysoft for the echo "script" | osacript
syntax!)
