Keypress Emulation

[Ale Muñoz]

Hi there,

I'm working on a script for an app, and at some point in the workflow I need to emulate a user's key presses.

Does JSTalk support that? How would I go about it?

I've checked the 'examples' folder in JSTalk but I've found nothing like it.

Thanks in advance!

I've worked on a little bit of built in support for this in the past, but it's been unreliable for reasons that I have yet to figure out. You can get around that though, by using System Events and AppleScript though:

var s = 'tell application "System Events" to keystroke "q" using command down';
[[[NSAppleScript alloc] initWithSource:s] executeAndReturnError:nil];

Wow, thanks Gus!

How would that work for multiple modifier keys? I'm trying to send the Ctrl + Alt + Command + Down Arrow combination.

Thanks in advance!

You need to give it the key code number for left arrow, and a list of modifiers.

tell application "System Events" to key code 125 using {control down, option down, command down}
