| 444 | 1327 Possible values for WHICH-FRAMES are |
| 428 | 1328 |
| 3025 | 1329 `visible' Consider only frames that are visible. |
| 1330 `iconic' Consider only frames that are iconic. | |
| 1331 `invisible' Consider only frames that are invisible | |
| 4207 | 1332 (this is different from iconic). |
| 3025 | 1333 `visible-iconic' Consider frames that are visible or iconic. |
| 1334 `invisible-iconic' Consider frames that are invisible or iconic. | |
| 1335 `nomini' Consider all frames except minibuffer-only ones. | |
| 1336 `visible-nomini' Like `visible' but omits minibuffer-only frames. | |
| 1337 `iconic-nomini' Like `iconic' but omits minibuffer-only frames. | |
| 1338 `invisible-nomini' Like `invisible' but omits minibuffer-only frames. | |
| 1339 `visible-iconic-nomini' Like `visible-iconic' but omits minibuffer-only | |
| 4207 | 1340 frames. |
| 3025 | 1341 `invisible-iconic-nomini' Like `invisible-iconic' but omits minibuffer-only |
| 4207 | 1342 frames. |
| 3025 | 1343 any other value Consider all frames. |
| 1344 | |
| 1345 If WHICH-FRAMES is omitted, `nomini' is used. A value for WHICH-FRAMES | |
| 1346 of 0 (a number) is treated like `iconic', for backwards compatibility. | |
| 444 | 1347 |
| 1348 If WHICH-FRAMES is a window, include only its own frame and any frame | |
| 1349 now using that window as the minibuffer. | |
| 1350 | |
| 1351 The optional third argument WHICH-DEVICES further clarifies on which | |
| 1352 devices to search for frames as specified by WHICH-FRAMES. | |
| 1353 If nil or omitted, search all devices on FRAME's console. | |
| 1354 If a device, only search that device. | |
| 1355 If a console, search all devices on that console. | |
| 1356 If a device type, search all devices of that type. | |
| 1357 If `window-system', search all window-system devices. | |
| 1358 Any other non-nil value means search all devices. | |
