2. Ctrl + R:

Renames (with refactor) a variable, method, class or a file. If applied for a variable, the variable is marked in a red rectangle. You type the new name and hit Enter, all references to that variable are updated:Press Esc to cancel renaming.If the object being renamed is a method or class, then the following dialog gets displayed:Enter a new name, and then click Refactor.You can also preview the changes by clicking the Preview button, and then a refactoring view gets displayed like this:Here you can compare the two versions: the current one versus the refactored one. Then click Do Refactoring to apply the changes.

3. Alt + Delete:

Use this shortcut to safely delete a variable, method or class. That means NetBeans will check for any references before deleting.For example, press Alt + Delete would bring the following dialog:Click Refactor. If references were found, that means you cannot safely delete the item, as shown in the following warning dialog:If there is no warning, NetBeans will delete the item because it’s safe.

4. Ctrl + M:

Moves members from one class to another, or moves a class from one package to another.Here’s the Move Members dialog:And here’s the dialog if the object being moved is a class:

5. Alt + Shift + M:

8. Alt + Shift + P:

Introduces a new parameter. This shortcut is useful in case you want to introduce a String literal, numeric literal, boolean literal or an expression to a method parameter.

Do you know that shortcuts help you accelerate your development productivity? Indeed, the more time you use keyboards, the higher efficiency you get. Therefore today I’m going to share with you the common shortcut keys which are designed for editing code in NetBeans IDE.NOTE: Standard shortcuts are not covered, such as Ctrl + Space (auto-complete), Ctrl + A (select all), Ctrl + Z (undo), and the like.

1. Ctrl + E or Shift + Delete: deletes the current line.
2. Ctrl + Delete: deletes the next word after the cursor. If it is a compound (i.e. using camel case like fileHandler), then only the first word is deleted.
3. Ctrl + Backspace: deletes the previous word before the cursor.
4. Alt + Shift + Up: Moves up the current line (or a selected block of code) by one line:
5. Alt + Shift + Down: Moves down the current line (or a selected block of code) by one line:
   
   
6. Ctrl + Shift + Up: Copies and moves up the current line (or a selected block of code) by one line:
7. Ctrl + Shift + Down: Copies and moves down the current line (or a selected block of code) by one line:
8. Shift + Enter: Inserts a blank line below the current line, regardless of position of the cursor in the current line (it’s very different than pressing Enter key alone):
9. Ctrl + Enter: Works similar to Shift + Enter, but insert a blank line above the current line if the cursor is at the beginning of line.
