When I use this script with applescript it works perfect:

tell application "System Events" to keystroke "r" using {option down, command down}

With execute shell command I use:

#!/usr/bin/osascript
tell application "System Events" to keystroke "r" using {option down, command down}

and nothing happens. on the output I get (see picture)

What am I making wrong? It is possible to send a keystroke from VUO ? thanks

It is what I had written. In script-editor it works correctly but not in Vuo node "execute shell command" and I can't find anywhere the correct notation for this node. I have tried:

`#!/usr/bin/osascript
tell application "System Events" to keystroke "r" using {option down, command down}`

but it doesn't run.

use AppleScript version "2.4"

use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use scripting additions

set shell to "tell application 'System Events' to keystroke 'r' using {option down, command down}"
set shellQuote to quoted form of shell
log {"shell is:", shell}
log {"shellQuote is:", shellQuote}
--tell application "System Events" to keystroke "r" using {option down, command down}

** Notice that I had to use single quotes instead of double to create the shell string

When I run this the properties are:

Shell:    

tell application 'System Events' to keystroke 'r' using {option down, command down}    

shellQuote:    

'tell application '\''System Events'\'' to keystroke '\''r'\'' using {option down, command down}'

From the Script Dictionary for System Events on the Text Class:

quoted form A rendering of the text string suitable for handing to the shell as an argument to a command. The text string is wrapped in single quotation marks and internal quotation marks are escaped.

You also may want to try the System Events Command:

key code key code (verb)cause the target process to behave as if key codes were entered (from Processes Suite) COMMAND SYNTAX key code integer or list of integer ¬ using using or list of using PARAMETERS Parameter Required Type Description direct parameter required integer or list of integer The key code(s) to be sent. May be a list. using optional using or list of using modifiers with which the key codes are to be entered

Thanks, technomorph.

Thanks, technomorph.

jfg,
Unfortunately, Vuo's Execute Shell Command executes commands in a sandbox, which prevents performing system-wide actions such as sending a keystroke. If you're trying to refresh a webpage (⌘⌥R is the shortcut for refreshing a webpage in Safari), then maybe you can use Vuo's Make Image from Web Page node.

Of possible interest is the Feature Request, Key event emulator.
