[FEATURE] Alt+arrows cursor movement

[makuke1234]

Is your feature request related to a problem? Please describe.
When using Alt+Left the editor should move the cursor to the previous memorised location. When using Alt+Right the editor should move the cursor to the next location.

Describe the solution you'd like.
The feature should only work when using mouse to change the cursor location. When clicking with the mouse somewhere that isn't the current cursor position, the current location should be memorised and pushed to array's end. When going back and doing a mouse click the remembered "next" movements should be discarded.
