Keyboard shortcut for switching focus between panes

[TessaI159]

I'm not sure if somebody else has already submitted this or not, the trello board won't load for me, and I'm not even sure if this the right place to do this but it can't hurt.
I would love to see a keyboard shortcut that would allow me to switch which view is active. I love the vertical split idea so I can see two documents at once, but it seems inconvenient that I need my mouse to switch focus between them.

@Tessag159 You can assign them with User Key map easily. Just Select User Key Map from Debug menu and paste the following key bindings. Then, reassign the keys to whatever you want.

        "Ctrl-1": "cmd.splitViewNone",
        "Ctrl-2": "cmd.splitViewVertical",
        "Ctrl-3": "cmd.splitViewHorizontal"

Update: actually, the key bindings above only allow you to switch between different split views, but not to set focus from one view to the other. So we still don't have any command to switch focus between split views.

@Tessag159 You can use Ctrl-Tab to navigate between recent documents, including switching across panes. There's also my File Navigation Shortcuts extension, which lets you switch to any open document quickly by typing a few characters of its name.

It should also be pretty easy for someone to write an extension that specifically jumps focus to a given pane (or toggles focus between the two panes -- unlike Ctrl-Tab regardless of whether the other pane's document was recently focused before or not). I'll mark this 'extension idea' in case anyone wants to implement that.

@Tessag159 you could also write an extension which registers a key to toggle between the two panes.

The code below should do it but I haven't tested it. You'll need to wire that up to a keyboard command. For that refer to the hello-world sample: https://github.com/adobe/brackets/wiki/Simple-%22Hello-World%22-extension

function switchPanes() {

    if (MainViewManager.getPaneCount() > 1) {
        var activePane = MainViewManager.getActivePaneId(),
            paneIds = MainViewManager.getPaneIdList(),
            index = paneIds.indexOf(activePane) + 1;

         if (index >= paneIds.length) {
            index = 0;
         }

         MainViewManager.setActivePaneId(paneIds[index]);
    }
}

Thank you guys so much, I'll get around to seeing if any of these suggestions work just as soon as I can.

Has anyone done any more work on this? I am a new developer and I thought I'd give this a try, but I don't want to duplicate efforts if an extension is already in progress.

[TessaI159]

I haven't done anything with it, and I doubt anybody else has either. Go ahead and give it a shot.

I've wrote extremly simple extension for toggling panes:

You can install it through extension manager.
Does it solve your problem?

I'd love to see this feature in the core too. Tagging as starter bug.

Hi @petetnt , Can I try adding this feature in the core? Thank you!
