ALT+TAB with the mouse cursor (or "pointing device") on the Konsole icon? No. But ALT+TAB anywhere else and a rectangle of stuff opens in mid-screen, but disappears when I reach for the mouse. --I only have one hand--.
But, a work-around may be to (1) select an empty workspace, (2) click on that Ubuntu icon and then (3) select "More Apps", then (4) chose "Installed" [and probably "see N more results"] and scroll down to "Konsole" and (5) click *that* icon. It looks like if you want more than one Konsole per Workspace, you just goto "(2)".
This newest version of Ubuntu is hard to get this set up. Do you know if there is a way of setting everything so that when I reboot, my apps are where they were? You or anybody else reading this?
