I’ve tried searching, but I couldn’t find any solutions without having to download other stuff.
I have never seen a way to do that here in the bbs. :o
If you’re more interested in the action itself rather than scripting for the action, pressing Control + 5 on the numeric keypad would be faster. This requires that Mouse Keys is enabled in System Preferences > Universal Access > Mouse.
If you’re interested in a script, this one can be saved as an application and run from the Dock (GUI scripting must be enabled):
tell application "System Events"
keystroke tab using command down
key down control
keystroke (ASCII character 53)
key up control
end tell
With Full Keyboard Access turned on, the script can be launched from the Dock by pressing Control + F3, using your left or right arrow keys if necessary, and pressing Return once the script is highlighted. No need to download to anything special for this approach. If desired, you can also use a 3rd-party application and assign a function key to launch the script.
Script tested using Mac OS 10.4.11
