365 | =head3 SELECTION |
|
|
366 | |
|
|
367 | You can select entries in the Schnauzer in a variety of ways: |
|
|
368 | |
|
|
369 | =over 4 |
|
|
370 | |
|
|
371 | =item Keyboard |
|
|
372 | |
|
|
373 | Moving the cursor with the keyboard will first deselect all files and then |
|
|
374 | select the file you moved to. |
|
|
375 | |
|
|
376 | =item Clicking |
|
|
377 | |
|
|
378 | Clicking on an entry will select the one you clicked and deselect all |
|
|
379 | others. |
|
|
380 | |
|
|
381 | =item Shift-Clicking |
|
|
382 | |
|
|
383 | Shift-clicking will toggle the selection on the entry under the mouse. |
|
|
384 | |
|
|
385 | =item Dragging |
|
|
386 | |
|
|
387 | Dragging will select all entries between the one selected when pushing the |
|
|
388 | button and the one selected when releasing the button. If you move above |
|
|
389 | or below the schnauzer area while drag-selecting, the schnauzer will move |
|
|
390 | up/down one row twice per second. In addition, horizontal mouse movement |
|
|
391 | acts as a kind of invisible horizontal scrollbar. |
|
|
392 | |
|
|
393 | =item Hint: double-click works while click-selecting |
|
|
394 | |
|
|
395 | You can double-click any image while click-selecting to display it |
|
|
396 | without stopping the selection process. This will act as if you normally |
|
|
397 | double-clicked the image to display it, and will toggle the selection |
|
|
398 | twice, resulting in no change. |
