Choose the right keymap

To view the keymap configuration, open the Settings/Preferences dialog Ctrl+Alt+S and select Keymap.

  • Use a predefined keymap

    RubyMine automatically suggests a predefined keymap based on your environment. Make sure that it matches the OS you are using or select the one that matches shortcuts from another IDE or editor you are used to (for example, Eclipse or NetBeans).

  • Tune your keymap

    You can modify a copy of any predefined keymap to assign your own shortcuts for commands that you use frequently.

  • Import custom keymap

    If you have a customized keymap that you are used to, you can transfer it to your installation.

Besides the default set of keymaps, you can add more as plugins (such as, keymaps for GNOME and KDE): open the Settings/Preferences dialog Ctrl+Alt+S, select Plugins and search for keymap in the Marketplace.

Learn shortcuts as you work

RubyMine provides several possibilities to learn shortcuts:

  • Find Action is the most important command that enables you to search for commands and settings across all menus and tools.

    Press Ctrl+Shift+A and start typing to get a list of suggested actions. Then select the necessary action and press Enter to execute it.

    Find Action
  • Key Promoter X is a plugin that shows a popup notification with the corresponding keyboard shortcut whenever a command is executed using the mouse. It also suggests creating a shortcut for commands that are executed frequently.

  • If you are using one of the predefined keymaps for your OS, you can print the default keymap reference card ...

    ... and keep it on your desk to consult it if necessary. This cheat sheet is also available under Help | Keymap Reference.

  • To print a non-default or customized keymap, use the Keymap exporter plugin.

Use advanced features

You can further improve your productivity with the following useful features:

  • Quick Lists

    If there is a group of actions that you often use, create a quick list to access them using a custom shortcut. For example, you can try using the following predefined quick lists:

    • Refactor this Ctrl+Alt+Shift+T

    • VCS Operations Alt+`

  • Smart Keys

    RubyMine provides a lot of typing assistance features, such as automatically adding paired tags and quotes, and detecting CamelHump words.

  • Speed search

    When the focus is on a tool window with a tree, list, or table, start typing to see matching items.

  • Press twice

    Many actions in RubyMine provide more results when you execute them multiple times. For example, when you invoke basic code completion with Ctrl+Space on a part of a field, parameter, or variable declaration, it suggests names depending on the item type within the current scope. If you invoke it again, it will include classes available through module dependencies. When invoked for the third time in a row, the list of suggestions will include the whole project.

  • Resize tool windows

    You can adjust the size of tool windows without a mouse:

    • To resize a vertical tool window, use Ctrl+Shift+Left and Ctrl+Shift+Right

    • To resize a horizontal tool window, use Ctrl+Shift+Up and Ctrl+Shift+Down
