|
355 | =head3 SELECTION |
|
|
356 | |
|
|
357 | You can select entries in the Schnauzer in a variety of ways: |
|
|
358 | |
|
|
359 | =over 4 |
|
|
360 | |
|
|
361 | =item Keyboard |
|
|
362 | |
|
|
363 | Moving the cursor with the keyboard will first deselect all files and then |
|
|
364 | select the file you moved to. |
|
|
365 | |
|
|
366 | =item Clicking |
|
|
367 | |
|
|
368 | Clicking on an entry will select the one you clicked and deselect all |
|
|
369 | others. |
|
|
370 | |
|
|
371 | =item Shift-Clicking |
|
|
372 | |
|
|
373 | Shift-clicking will toggle the selection on the entry under the mouse. |
|
|
374 | |
|
|
375 | =item Dragging |
|
|
376 | |
|
|
377 | Dragging will select all entries between the one selected when pushing the |
|
|
378 | button and the one selected when releasing the button. If you move above |
|
|
379 | or below the schnauzer area while drag-selecting, the schnauzer will move |
|
|
380 | up/down one row twice per second. In addition, horizontal mouse movement |
|
|
381 | acts as a kind of invisible horizontal scrollbar. |
|
|
382 | |
|
|
383 | =item Hint: double-click works while click-selecting |
|
|
384 | |
|
|
385 | You can double-click any image while click-selecting to display it |
|
|
386 | without stopping the selection process. This will act as if you normally |
|
|
387 | double-clicked the image to display it, and will toggle the selection |
|
|
388 | twice, resulting in no change. |
