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