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.

ALT + Esc looks like it's a custom keyboard shortcut that either you, some program or someone else put into place. If both pop-ups for the shortcuts look the same, they are the same.

Check System Settings>Keyboard>Custom Shortcuts to see if there are any set.
