... Typeface 字样 undo command 作废命令 Unexpected halt 意外停机 ...
你可以使用重做命令来扭转撤销命令进行的操作。
When the undo command is unavailable (dimmed), you cannot undo the previous action.当撤销命令不可用时(变灰),则不能撤销之前的操作。
Locks are also released if the pending changes for a file are undone by using the undo command.如果使用撤消命令撤消对文件挂起的更改,也会释放锁。
