Is it possible via Automator, an app, applescript, etc. to automatically press a key (i.e. "g") every 60 seconds?
You can do this in AppleScript, iff you've enabled access for assistive devices:
tell application "System Events" to keystroke "," using command down
This will (obviously) invoke cmd-,.
If, for some reason, you can't enable access for assistive devices, then it's pretty easy to do this in code (by creating a
CGEventRef and then posting it to the system, essentially). If you'd like help with that, then head over to stackoverflow.com, where that question has been asked a few times.
As for getting this to happen every 60 seconds, you could turn it into a launch agent and let launchd do it for you:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.stackexchange.apple.12692</string> <key>Program</key> <string>/usr/bin/osascript</string> <key>ProgramArguments</key> <array> <string>osascript</string> <string>-e</string> <string>tell application "System Events" to keystroke "," using command down</string> </array> <key>ServiceDescription</key> <string>Auto Keypress</string> <key>StartCalendarInterval</key> <dict> <key>Second</key> <integer>0</integer> </dict> </dict> </plist>
Toss that in ~/Library/LaunchAgents and you should be good to go (once you load the plist and/or log out and log back in).
Use the "Watch Me Do" to enter "G," then use the pause action to pause for 60 sec, then the loop action and select "Loop Automatically."
