Right-Alt doesn't work for adding multiple cursors (necessary for ChromeOS)

[Zacqary]

Left-Alt+Click on ChromeOS maps to a right click. This makes it impossible to add multiple cursors on Cloud9. This behavior is built into ChromeOS and is impossible to disable.

Right-Alt+Click doesn't map to a right click on ChromeOS, but it doesn't add a second cursor in Cloud9. Allowing users to add a second user using Right-Alt instead of just Left-Alt should be an effective workaround when using Cloud9 on a Chromebook.

Ace accepts both left and right Alt as click modifiers. It just uses event.altKey property here. Which keyboard layout do you use? with some keyboard layouts left alt is interpreted as alt-gr and sets both event.altKey and event.ctrlKey to true.

You're absolutely right, I had US Extended on. I feel really stupid.

That probably means ChromeOS actually does interpret Right Alt as a right click as well, so that's back to square one.

Is there a way to change the key binding for clicking to add multiple cursors? I wasn't able to find it in the Preferences pane. On Jun 20, 2015 8:07 AM, "Harutyun Amirjanyan" notifications@github.com wrote:

Yup this one is driving me crazy too. Maybe custom keybindings in c9?

[danferth]

yes you can! open preferences and select key bindings to edit addCursorBelow and whatnot, I changed it to ctrl+alt+l and boom bobs your uncle!
