问题
I was wondering if it were possible in Eclipse PDT to reopen a closed tab by mistake.
For example in Firefox I can do Ctrl + Shift + T.
回答1:
Yes it's possible. Close a tab and hit the left yellow arrow in the Eclipse menu bar above.
You can adjust the keyboard shortcut for that in the eclipse preferences under General > Keys.
On Mac it's ⌘ + [
回答2:
Try Alt + left arrow that will go backward in history - if tab is closed it will reopen it.
回答3:
Navigating back through the edit history does work sometimes, but not if you close the tab without actually activating it. You can also try Alt + F to access the file menu then hit a number to access the appropriate file in the recent file list.
回答4:
You may also find the Extended VMM Presentation plugin useful. Among others, it provides a list of the last several closed tabs.
Keep in mind that so far it does not seem to work with the new Eclipse Juno.
