 {
 UNSPECIFIED = 0, // illegal
 NOP, // Undo/redo will ignore this entry. Only forces the start of a new stack
 CHANGED, // params of items have a value changed: undo is made by exchange
 // values with a copy of these values
 NEWITEM, // new item, undo by changing in deleted
 DELETED, // deleted item, undo by changing in deleted
 LIBEDIT, // Specific to the component editor (symbol_editor creates a full copy
 // of the current component when changed)
 LIB_RENAME, // As LIBEDIT, but old copy should be removed from library
 EXCHANGE_T, // Use for changing the schematic text type where swapping
 // data structure is insufficient to restore the change.
 DRILLORIGIN, // origin changed (like CHANGED, contains the origin and a copy)
 GRIDORIGIN, // origin changed (like CHANGED, contains the origin and a copy)
 PAGESETTINGS, // page settings or title block changes
 REGROUP, // new group of items created (do not use GROUP to avoid collision
 // with an header on msys2)
 UNGROUP // existing group destroyed (items not destroyed)
