`CTRL + SHIFT + ALT + N`
+

`CTRL + SHIFT + N`
+

## Actions
[`CTRL + SHIFT + A`](https://makandracards.com/makandra/6637-rubymine-find-and-execute-a-menu-action-by-its-name)
+
: Find and execute a menu action by its name
`ALT + ENTER` with the cursor on a highlighted section (e.g. underline)
+
: Opens a context menu offering actions for the highlighted section.
`ALT + INS`
+
: Create a new file/directory/... . List does filter-as-you-type, so by typing `f` or `d` you can select either `file` or `directory` and press `Enter`. Additional boost: When typing a file name, you may write intermediate directories as part of the file name. RubyMine will create any missing directory.
`ALT + J`
+
: Select the word under the cursor, then select each next occurrence of this word in the code (multiple selection). Power feature!
`Press CTRL twice, and then without releasing it, press down arrow keys`
+
: The new carets are added to the columns below. Power feature!
`CTRL + SHIFT + ALT + C`
+
: Copy the current file path with line number to the clipboard. This is especially helpful to run a single feature/spec: Just paste the reference into your terminal (you need to "unmark" the test directories "as test sources root" to get a path relative to the project root).
`CTRL + D` with two files selected in the project pane (click with CTRL)
+
: Diff the selected files
`CTRL` + `SHIFT` + `Backspace`
+
: Move caret to position of last edit
`CTRL` + `ALT` + Left arrow
+
: Move to last position (see [this card](https://makandracards.com/makandra/496446-rubymine-how-to-restore-the-back-to-last-position-shortcut-on-ubuntu-20-04) for Ubuntu 20.04 with Gnome)
`CTRL` + `ALT` + `L`
+
