I realize middle-clicking on a Launcher icon opens a new instance, but my mouse doesn't have a good middle-click option (clicking the scrollwheel works for this, but it's cumbersome). My workflow tends to involve numerous windows for programs such as terminal and Chrome. Currently, terminal opens new windows when I click the Launcher icon, but Chrome and Nautilus do not.
I found out how to list all the keys associated with
org.compiz.unityshell by way of an article on OMG! Ubuntu!, and got this list:
user@comp> gsettings list-keys org.compiz.unityshell override-decoration-theme disable-show-desktop launcher-switcher-forward reveal-trigger reveal-pressure alt-tab-prev-window launcher-capture-mouse stop-velocity panel-opacity-maximized-toggle automaximize-value spread-app-windows panel-first-menu decay-rate alt-tab-bias-viewport background-color lock-screen backlight-mode dash-blur-experimental edge-responsiveness show-minimized-windows inactive-shadow-color low-graphics-mode spread-app-windows-anywhere alt-tab-timeout switch-strictly-between-applications autohide-animation shadow-y-offset inactive-shadow-radius menus-discovery-duration launcher-switcher-prev menus-fadeout shadow-x-offset icon-size overcome-pressure dash-tap-duration execute-command alt-tab-forward show-launcher edge-passed-disabled-ms launcher-opacity show-desktop-key show-hud scroll-inactive-icons disable-mouse alt-tab-next-window num-launchers menus-fadein panel-opacity launcher-hide-mode active-shadow-radius menus-discovery-fadeout keyboard-focus alt-tab-prev urgent-animation active-shadow-color launcher-minimize-window alt-tab-prev-all launch-animation menus-discovery-fadein show-menu-bar alt-tab-forward-all shortcut-overlay user@comp>
However, none of these look very promising. I have also found other questions wanting to do exactly the opposite of what I want to do, but I couldn't determine from those questions how to reverse it.
Is there a way to make the Unity Launcher open new windows for all programs when left-clicking and not just when middle-clicking?
