Blender uses the common Ctrl + z keybinding to undo any action, and Ctrl + Shift + z to redo (undo an undo). This is familiar to most users, but not always convenient, for example, for MacOS users. If necessary, the undo and redo keybindings can be easily changed.

Actually, in Blender, undo and redo operations are implemented as standard API operators. If needed, they can even be called from your own scripts and add-ons.
The undo operator:
|
1 |
bpy.ops.ed.undo() |
And the redo operator:
|
1 |
bpy.ops.ed.redo() |
This approach allows the keyboard shortcuts bound to these operator calls to be easily changed through the KeyMap settings.
Open the Preferences area and switch to the “Keymap” tab.
In the search field, type “undo” or “redo,” depending on what you want to change.
Expand the settings field for the resulting Screen – Undo and Screen – Redo operators.
Change the keyboard shortcuts for these operations to those that are most convenient for you. You can then undo and redo in Blender by pressing the new keyboard shortcuts.
Don’t forget to click “Save Preferences” (if you have auto-saving settings disabled) so that your changes are saved for future Blender launches.
