Selecting Text in the Editor
The basic way to select a piece of text is to extend the selection with the mouse cursor. RubyMine, as a keyboard-centric IDE, suggests to use navigation keys to make selections.
You can opt to select pieces of text, or select rectangular fragments in the column mode, extend and shrink the selection, use multiselection, and sticky selection.

Alternative ways to select code

- Keeping the middle mouse button pressed, drag your mouse pointer to select the desired area.
- Press Shift+Alt and the middle mouse button. This is specially helpful, if you want to avoid dragging.
To extend selection from the word at caret to the piece of code the caret is contained in, do one of the following:
- On the main menu, choose
- Press Ctrl+W to select the word where the caret is currently located.
- Press Ctrl+W successively to extend selection to the next containing node (for example, an expression, a paired tag, an entire conditional block, a method body, a class, a group of vararg arguments, etc.)

To shrink selection in the reverse order (from the outermost container to the word where the caret currently resides), do one of the following:
