Key Bindings
The command a key binding invokes may be modified with the User Interface > Keyboard > Custom Key Bindings preference. A custom key binding will override any binding found in the current keyboard personality.
To add a binding, click the Insert button, press the key binding you wish to use in the Key field, and then enter the name of the command to invoke in the Command field. To unbind a key that Wing defines by default, leave the Command field blank.
To determine what command a key is currently bound to, select Command by Name from the Edit menu, type describe-key-briefly and then press the key binding followed by Enter.
Key Bindings
Key bindings consist of one or more key presses, including any regular key and one or more modifier keys (Shift, Ctrl, Alt, and/or Command). Multiple modifiers may be pressed at once; Ctrl-Shift-X is distinct from Ctrl-X.
The Shift key is treated as a modifier only for keys where there is a lower case and upper case variant. For example, Shift-M is a valid binding for capital M while Shift-9 will result in a different key binding (Parenleft on a US keyboard). The dialog for adding key bindings from the Custom Key Bindings preference takes care of this detail.
Key bindings may consist of multiple key strokes in a row, such as Ctrl-X Ctrl-U, Ctrl-X A, or Esc X Y Z.
Commands
The command for a key binding may be any of Wing's internal commands, as documented in the Command Reference, or (in Wing Pro and Wing Personal) any user-defined command provided by an extension script.
To disable a key binding, leave the command field blank.
If multiple comma-separated commands are specified, the key binding will execute the first available command in the list. For example, specifying debug-restart, debug-continue as the command will first try to restart an existing debug session, and if no debug session exists it will start a new one.
Some commands take arguments, which can be specified in the binding, for example using enclose(start="(", end=")") in the Command field will enclose the current selection with (). Any unspecified arguments that do not have a default defined by the command will be collected from the user, either in a dialog or in the data entry area at the bottom of the IDE window.
Key bindings defined by the keyboard personality or overridden by the Custom Key Bindings preference will be shown in menu items that implement the same command. If a command is given more than one key binding, only the last binding found will be displayed, although all the bindings will work from the keyboard.
The Alt Key on macOS
On macOS, the User Interface > Keyboard > Alt Key preference allows selecting one or both of the Option keys or the Command keys to act as the Alt key modifier for key bindings.
This preference should be set according to keyboard type, so that key bindings in Wing do not prevent entering characters composed with the Option keys.
For example, on German keyboards, [, ], and other common symbols are entered with using Option key. In those cases, setting the preference to "Left Option key" frees up the right Option key for entering characters and dedicates the left Option key to triggering key bindings.
When Command is used for Alt, the binding for Alt-<key> takes precedence over any binding for Command-<key> for the same key.
