modify-viewport | ‘boolean’ | ‘false’ | Allow undo/redo operations to change pan and zoom. |
undo-control | ‘boolean’ | ‘true’ | Controls if the undo is enabled or not. Since 1.9.10. |
undo-type | ‘string’ | ‘disk’ | Possible values: ‘disk’, ‘memory’. Controls what kind
of medium is used for storing undo data. The ‘disk’ mechanism
is nice because you get undo-level number of backups of the schematic
written to disk as backups so you should never lose a schematic due to
a crash. Since 1.9.10. |
undo-levels | ‘int’ | ‘20’ | Determines the number of levels of undo. Since 1.9.10. |
undo-panzoom | ‘boolean’ | ‘false’ | Controls if pan or zoom commands are saved in the undo list. If this
is enabled, then a pan or zoom will be considered a command and can be
undone. Since 1.9.10. |
