Useful Eclipse ADT Shortcut keys

Ctrl + Shift + T: Open type: Displays the Open Type dialog box to open the type in the editor. The Open Type Selection dialog box displays all the types that exist in the workspace, such as classes, interfaces, and so on.
Ctrl + Shift + R: Open resource: Opens the Open Resource dialog box to open any resource in the workspace. You can quickly open any file in the Package Explorer without having to browse for it. Using this shortcut, you can open a dialog box and enter the file or wildcard character you want to find. (Ctrl + O similar to source insight)
Ctrl + O: Quick outline: Opens a lightweight outline of the currently selected type. Opening a member variable directly in a file (such as a field, method), especially if there are many similar method names, will become very useful.
Ctrl + L: Enter number of rows: Go to Line: Opens a dialog box that allows you to enter the line number that the editor should jump to. Applies only to editors. Enter the line number to quickly jump to the nth row in the source file. (Ctrl + O similar to source insight)
Ctrl + Q: Previous edit position: Displays the location of the previous edit operation, returning to the nearest modified location. Even if you look at different files, you can use this shortcut to find the location of your most recent changes to the file. Especially when the file is larger, it is more useful.
Ctrl + T: Quick type hierarchy: Opens the Lightweight hierarchy viewer for the currently selected type, enabling you to quickly go to a supertype or subtype. (Inheritance is too important for object-oriented languages, but now there's a problem, after inheriting the template class, you can't analyze it.)
Ctrl + E: Quickly jump to another editor. Note that CTRL + F6 can also implement this function, in the use of the time to pay attention to their similarities and differences. (It feels like a quick version of CTRL + Shift + R, but only open tag files can be opened)
Ctrl +./ctrl +,: Quickly navigate to a problem in a file (such as errors, warnings, etc.)
Alt +←and Alt +→: Go back and forth to the file you have consulted
F3: Quickly go to a type declaration. You can also hold down CTRL and click the hyperlink variable or the class or any declarations you want to see. (Fast jump, the world is in use)
Ctrl +/: Note the bank
Ctrl + D: Delete Bank
Ctrl + SHIFT + F: Plastic (good, but use caution, unless your configuration and code style, otherwise it will cause you to commit the code chaos, I paid a half-time price)
Ctrl+shift+x the text that is currently selected is all stale lowercase
Ctrl+shift+y turns the currently selected text to lowercase
Ctrl+m maximize the current edit or view (and vice versa)
Ctrl+j forward Incremental lookup (after pressing CTRL+J, each letter editor you enter provides a quick match to navigate to a word, if not, it is not found in the Stutes line, it is especially useful to look up a word, this function idea was there two years ago) (Dick exploded, Same as vim normal mode search)
Alt+↓ the current line and the next line of interaction (especially useful, can be omitted first cut, then pasted)
Alt+↑ the current line and the upper row interaction position (IBID.)
