Difference between alt+tab and alt+escape
On my GNOME + Ubuntu system, both Alt+Enter and Alt+Escape+ switch between windows.
What exactly is the difference, if any, between them?
Alt+Tab switches between different programs on the same workspace (if activated) with a popup.
Alt+Esc switches between different programs without a popup.
Alt+` (key below Esc) switches between different instances of a program.
Super+Tab switches between all programs regardless of the workspace (if activated) with a popup.
Alt escape is for the next window without the Alt-Tab popup. So it's the same as Alt-Tab but without the popup.
