Add Shortcuts to RStudio

Source: R/add_shortcuts.R
add_rstudio_shortcuts.Rd

Add up to 100 fully configurable shortcuts to RStudio. Store your shortcuts in .shrtcts.yaml in your R home or OS home directory. Then add add_rstudio_shortcuts() to your ~/.Rprofile to load the shortcuts when starting R. Your shortcuts will automatically appear in the Addins window (if not, try restarting your R session one more time). Your shortcuts can be arbitrary functions written inline or functions from other packages. You can set their names and even assign keyboard shortcuts to your shrtcts. See detailed sections below.

Usage

add_rstudio_shortcuts(path = NULL, set_keyboard_shortcuts = FALSE)

example_shortcuts_yaml()

example_shortcuts_r()

Arguments

path

The path to your .shtrcts.yaml file. If NULL, shrtcts will look in your R or OS home directory (via fs::path_home_r() or fs::path_home()). You can set this path via the global option "shrtcts.path". For more information, see the help documentation on paths.

set_keyboard_shortcuts

If TRUE, will attempt to set the RStudio keyboard shortcuts in addins.json.

Details

shrtcts R Format

Use the following template to organize your .shrtcts.R. You can write each shortcut in regular R code, annotated with roxygen2 inline documentation comments. The comment format uses standard roxygen2 formatting, with a few additional roxygen tags specifically for shrtcts

#' Say Something Nice
#'
#' A demo of cool things.
#'
#' @interactive
#' @shortcut Ctrl+Alt+P
praise::praise

roxygen2 Tags

shrtcts recognizes the following roxygen tags. Tags are optional unless otherwise specified.

  • @title (required): The name of the shortcut’s addin in RStudio. The tag itself is not required, the first line of untagged text (#' Say Something Nice above) is interpreted as the title.

  • A function, either exported from another package, e.g. praise::praise or as an anonymous or named function provided immediately below the roxygen2 comments section. (Function names are ignored if provided).

  • @description: A description of the shortcut. Can be specified with the roxygen tag or it can be the first paragraph of untagged text after the title line.

  • @interactive: Whether or not the shortcut’s addin should be executed interactively.

    Non-interactive addins are run in the background, without alerting the user and without providing a mechanism for the user to cancel the function.

    If the shortcut is interactive and calls a function stored in another package, the code to execute the function will be displayed in the console, rather than the placeholder shortcut from shrtcts.

  • @id: An integer id (< 100) used to link the shortcut to a specific placeholder function in shrtcts. For example, #' @id 5 will link the provided shortcut to shrtcts:::shortcut_05(). This is particularly useful if you have a keyboard shortcut linked to your shortcut, although the need for this tag is mitigated by the @shortcut tag.

  • @shortcut: A combination of keys to be used as a keyboard shortcut in RStudio. Keyboard shortcuts are only applied if set_keyboard_shortcuts is set when calling add_rstudio_shortcuts(). This option is disabled by default.

Where to Store Your Shortcuts

Save your shortcuts R (or YAML) file as .shrtcts.R or .shrtcts.yml in your home directory or in the .config directory in your home directory — use fs::path_home_r() or fs::path_home() to locate your home directory. In other words: ~/.config/.shrtcts.R or ~/.shrtcts.yml.

You can test that shrtcts correctly finds your shortcuts file – or confirm which file will be used by shrtcts – using locate_shortcuts_source().

Install Your Shortcuts

Run add_rstudio_shortcuts() to install your shortcuts. You’ll need to restart your R session for RStudio to learn your shortcuts.

To also update your shrtcts-related keyboard shortcuts, set set_keyboard_shortcuts = TRUE. This will update the keyboard shortcuts stored in RStudio’s addins.json, typically stored in ~/.config/rstudio/keybindings (>= 1.3) or ~/.R/rstudio/keybindings (< 1.3). If this file is stored in a non-standard location in your setup, you can provide set_keyboard_shortcuts with the correct path to addins.json. Whenever shrtcts updates the shortcut keybindings, a complete restart of RStudio is required (hint: use usethis:::restart_rstudio()).

RStudio Keyboard Shortcuts

Once you’ve setup an RStudio Addin via shrtcts, there are two ways to link the shortcut’s addin to a keyboard shortcut.

You can verify and list the current shortcuts and their keyboard bindings with list_shortcuts().

shrtcts::list_shortcuts()

##                                name       addin shrtcts_keybinding rstudio_keybinding
## 1                 10 random numbers shortcut_01               <NA>               <NA>
## 2 New Temporary R Markdown Document shortcut_02   Ctrl+Alt+Shift+T   Ctrl+Alt+Shift+T
## 3   A Random Number Between 0 and 1 shortcut_03               <NA>               <NA>
## 4                Say Something Nice shortcut_97         Ctrl+Alt+P         Ctrl+Alt+P

Declare Keyboard Shortcuts in .shrtcts.R

You can use the @shortcut tag to declare the shortcut in .shrtcts.R (or shortcut: in the YAML .shrtcts.yml).

To update the keyboard shortcuts (for shrtcts only!), set set_keyboard_shortcuts = TRUE when calling add_rstudio_shortcuts(). If you use this method, shortcuts set manually in RStudio will be overwritten, so you should choose one method or the other.

  • .shrtcts.R

    #' Say Something Nice
#'
#' @description A demo of cool things
#' @interactive
#' @shortcut Ctrl+Alt+P
praise::praise

  • .shrtcts.yml

    - Name: Say Something Nice
  Description: A demo of cool things
  Binding: praise::praise
  shortcut: Ctrl+Alt+P
  Interactive: true

A full restart of RStudio is required whenever shrtcts udpates the shortcut keybindings. shrtcts only manages keybindings for its own addins, and it doesn’t check for conflicting key combinations, so you may want to double check the RStudio menu.

If anything goes wrong, a backup of the keybindings are saved as addins.json.bak in the same folder where addins.json was found. Use location_addins_json() to find this file.

Setting Keyboard Shortcuts via RStudio Menus

You can create a keyboard shortcut for the addin using the Tools > Modify keyboard shortcuts menu.

If you create a shortcut for an addin via the menu, it’s a good idea to set the id of the shortcut.

You can set your keyboard shortcuts manually in your .shrtcts.R or .shrtcts.yml files, using the @shortcut tag or shortcut: item name.

shrtcts YAML format

shrtcts initially provided a way to specify the shortcuts in a YAML file. This made sense because everything is YAML these days, so why not add yet another YAML config file to the mix? But writing R code inside YAML is, um, less than ideal. So it’s no longer recommended, but it is still supported (for now). To convert existing shortcuts from YAML to the roxygen2 format, use the internal shrtcts:::migrate_yaml2r() function.

Use the following template to organize your .shrtcts.yaml. Each shortcut is a YAML list item with the following structure:

- Name: Make A Noise
  Description: Play a short sound
  Binding: beepr::beep
  Interactive: true
  id: 42
  shortcut: Ctrl+Shift+B

Functions

  • example_shortcuts_yaml: An example .shrtcts.yml file.

  • example_shortcuts_r: An example .shrtcts.R file.

Examples

# Add shortcuts to ~/.shrtcts.yaml (see help above)

# Add this to your ~/.Rprofile to automatically load shortcuts
if (interactive() && requireNamespace("shrtcts", quietly = TRUE)) {
  shrtcts::add_rstudio_shortcuts()
