  • Great utility for Touchscreen Expose use

    Just found this while flipping through an OS X hack book, published by the same fine folks as Geek My Ride. Apparently, aside from mouse buttons, active screen corners, and function keys, there is another, hidden method for activating Expose, called the blob. You won't find it in any menues, but two quick lines of code in Terminal will bring the little guy up. It's basically just a round, opaque blue button (perfect for a TS) that appears on the desktop (and can be placed anywhere AND reskinned!), and serves the same purpose as the F9 default Expose action. Not such a huge deal, unless you are running VPC with no keyboard or mouse, like me. Once VPC got into full screen mode, I used to have no way to get back to OS X without a physical keyboard or mouse, since the touchscreen doesn't do active corners. But this little blob stays on top of the VPC window, even in full screen. Fixed the whole issue! I'll put up a screenshot when I get a chance, and if anybody is interested in the code or more details, feel free to ask.

    I have the same problem that you described while using VPC in full screen mode.

    Care to share the expose hack? Thanks in advance.

      This is how ExposŤ blob looks like:



      an this is how to turn it on:

      in terminal:
      Code:
      defaults write com.apple.dock wvous-olddesktop -bool false; killall Dock
      To turn it off / back to normal:
      Code:
      defaults write com.apple.dock wvous-olddesktop -bool true; killall Dock
      Have fun! I love it.

        huh, thats a different one and a different line of code than I had. Mine is just a little round button. Does that one work like the F10 key as opposed to F9, like mine? In any case, the code for mine is:

        defaults com.apple.Dock wvous-floater -bool true

        and then reset the dock with

        killall Dock

        Still haven't had a chance to get a screenshot yet, I'll be on vacation for a few days. But if anybody tries it and can post a screenshot before I get back, be my guest.

        Anybody know if there's a Dashboard blob? I would love to have a similar button to bring up dashboard when I'm in Windows. That would take quite a few clicks out of messing with VPC iGuidance and iTunes music at once.

            Yeah, that works! But the correct command syntax is:
            defaults write com.apple.Dock wvous-floater -bool true ; killall Dock
            And the kill-command at the end let's do this with one command (line).

            But the thing is... What to do with this button? It isn'nt really useful... (for me)...

            ...but such a button to activate Dashboard would be nice. At this time Dashboard is disabled in my car because of unuseable activation via touchpanel.

              Exactly. I want one too! Haha. I did do a defaults read on com.apple.dashboard and found nothing that looked similar to floater. Anyone know if this type of thing would be hard to write?
