I've installed (sudo apt-get install indicator-synapse), and I see the icon on the wingpanel. However, I can't activate it with any shortcut (ctrl-space doesn't work, which I though was the default), and can't find the entry in dconf-editor (net/launchpad/indicator-synapse) to change the shortcut!

  • Did you tried alt+f2 and than type indicator-synapse?

After installing synapse you should either restart wingpanel or log out and back in.

To restart wingpanel: killall wingpanel

The default indicator-synapse shortcut is: Alt+Super+Space

Details here:

install indicator synapse

Configure synapse

    thanks, Alt + Super + Space works. however, the config file the link indicates seems to be for synapse rather than indicator-synapse :/ Commented Sep 27, 2015 at 8:59

This solution worked for me originally posted by Karut on Launchpad:

Manually installing a newer (sucessfully built) build of synapse (529) actually solves this problem. Once you update synapse via package manager the problem of course will reappear.

Download it here.

    same problem: it installs fine and I can use it with super + alt + space, but still can't find where to change the hotkey. Commented Sep 29, 2015 at 20:17

There is a work around for this, using xdotool. This tool lets you simulate keyboard input and mouse activity, move and resize windows, etc. It does this using X11's XTEST extension and other Xlib functions.

Here, we are going to find the coordinates of the mouse, and emulate a mouse click on the synapse indicator using a command and set a shortcut key for the command.

Step 1: Install xdotool.

sudo apt-get install xdotool

Step 2: Move your mouse over the synapse icon and get mouse location

xdotool getmouselocation

You should get output like this:

x:1105 y:14 screen:0 window:39845936

Step 3: Add keyboard shortcut for indicator

Go to System Settings -> Keyboard -> Shortcuts -> Custom Shortcuts.

Click the + and enter the below command:

xdotool mousemove x y click 1 mousemove restore

Replace x and y with the values you got. Set the shortcut as Ctrl + Space Logout and Login again.


  • neat. will try this out - do you know how well it would work changing monitor configurations? I do that fairly often. Commented Nov 14, 2015 at 11:32
  • You'll have to change it every time. Another problem with this method is, if more icons (like when Skype is launched) occur, the setting won't work. I'm looking for a way to set a fixed position for the icons.
