Capture keyboard input?
Hi all,
Just wondering if Gauc has the ability to capture all keyboard input? I can't tell you how many times I've accidentally closed the whole tab while typing (CTRL + W)..
Please let me know if this is a possibility, thanks!

Thanks for the information, everyone. I will try out a few different browser configurations.

I forgot about the OS and Browser eating keys before you get them. With most browsers you can stop your browser from responding to those OR pop up a warning so it doesn't just happen without confirmation.

Guacamole already attempts to capture absolutely all keyboard input.
It's up to the OS and the browser to decide which key events to actually expose to JavaScript. Keyboard events for shortcuts reserved by the OS (Ctrl+Alt+Del, Alt+Tab, etc.) are typically eaten by the OS before they reach the browser, and keyboard events for shortcuts reserved by the browser (such as Ctrl+W) are typically eaten by the browser before they reach JavaScript.
Some browsers, Chrome included, will allow bookmarks to be saved to the desktop or home screen, and give the webapps bookmarked in such a manner access to additional keystrokes. If the browser you're using has this feature, that may help things. Beyond that, it's a security feature of the browser that web applications cannot take full control of the keyboard, and there's nothing that can be done within JavaScript to alter this. As long as the key event actually happens within JavaScript, Guacamole will handle it and pass it along to the remote desktop.

Ah, I misunderstood and that makes sense since you mentioned closing windows... So you want to "ignore" a key or key combination? I don't think it's built-in but I would start with the JS libraries. Between guacKey.js and Keyboard.js you can probably add a bit of code to ignore keys/key combos you want ignored. Sorry if I'm still misunderstanding what you're asking for. AFAIK, there's no Guacamole UI for configuring keys or key combos you want to ignore; for that I would defer to the experts.

Hi Ryan,
I am not looking to log keyboard events, I'd like to find a way for keyboard hot keys/combos to be 'captured' within the active session and not interrupted by the client OS (things like CTRL + ALT + DEL or CTRL + W).
Do you know if this is possible or shall I submit a feature request?

There's a key handler function in guacd (user-handler.c). You'd have to implement your own handler/function to do something like logging.

Anthony,
Yes, this is possible, but not by any sort of existing configuration -
you'd have to modify the source code of Guacamole to capture the specific
key strokes you're interested in. The Guacamole client uses this with CTRL
+ SHIFT + ALT to display the user menu on the left-hand side of the page
while you're connected.
Regards,
Nick
