226 The keybinding API allows you to add keyboard shortcuts that trigger actions in | |
227 your extension. An action can be opening the browser action or page action popup | |
228 or sending a command to the extension. | |
229 </p> | |
230 <h2 id="manifest">Manifest</h2> | |
231 <p> | |
232 In addition to the "experimental" permission you must declare the "keybinding" | |
233 permission in your extension's manifest to use this API and set manifest_version | |
234 to (at least) 2. | |
235 </p> | |
236 <pre>{ | |
237 "name": "My extension", | |
238 ... | |
239 <b> "permissions": [ | |
240 "experimental", | |
241 "keybinding", | |
242 ]</b>, | |
243 ... | |
244 }</pre> | |
245 <h2 id="usage">Usage</h2> | |
246 <p>The keybinding API allows you to define specific commands, and bind them to a | |
247 default key combination. Each command your extension accepts must be listed in | |
248 the manifest as an attribute of the 'commands' manifest key. Note: Combinations | |
249 that involve Ctrl+Alt are not permitted in order to avoid conflicts with the | |
250 AltGr key.</p> | |
251 <pre>{ | |
252 "name": "My extension", | |
253 ... | |
254 <b> "commands": { | |
255 "toggle-feature-foo": { | |
256 "suggested_key": { | |
257 "default": "Ctrl+Shift+Y", | |
258 "mac": "Command+Shift+Y" | |
259 }, | |
260 "description": "Toggle feature foo" | |
261 }, | |
262 "_execute_browser_action": { | |
263 "suggested_key": { | |
264 "windows": "Ctrl+Shift+Y", | |
265 "mac": "Command+Shift+Y", | |
266 "chromeos": "Ctrl+Shift+U", | |
267 "linux": "Ctrl+Shift+J" | |
268 } | |
269 }, | |
270 "_execute_page_action": { | |
271 "suggested_key": { | |
272 "default": "Ctrl+E" | |
273 "windows": "Alt+P", | |
274 "mac": "Option+P", | |
275 } | |
276 } | |
277 }</b>, | |
278 ... | |
279 }</pre> | |
280 <p>In your background page, you can bind a handler to each of the commands | |
281 defined in the manifest (except for '_execute_browser_action' and | |
282 '_execute_page_action') via onCommand.addListener. For example:</p> | |
283 <pre>chrome.experimental.keybinding.onCommand.addListener(function(command) { | |
284 console.log('Command:', command); | |
285 }); | |
286 </pre> | |
287 <p>The '_execute_browser_action' and '_execute_page_action' commands are | |
288 reserved for the action of opening your extension's popups. They won't normally | |
289 generate events that you can handle. If you need to take action based on your | |
290 popup opening, consider listening for an 'onDomReady' event inside your popup's | |
291 code. | |
