372=head3 SELECTION
373
374You can select entries in the Schnauzer in a variety of ways:
375
376=over 4
377
378=item Keyboard
379
380Moving the cursor with the keyboard will first deselect all files and then
381select the file you moved to.
382
383=item Clicking
384
385Clicking on an entry will select the one you clicked and deselect all
386others.
387
388=item Shift-Clicking
389
390Shift-clicking will toggle the selection on the entry under the mouse.
391
392=item Dragging
393
394Dragging will select all entries between the one selected when pushing the
395button and the one selected when releasing the button. If you move above
396or below the schnauzer area while drag-selecting, the schnauzer will move
397up/down one row twice per second. In addition, horizontal mouse movement
398acts as a kind of invisible horizontal scrollbar.
399
400=item Hint: double-click works while click-selecting
401
402You can double-click any image while click-selecting to display it
403without stopping the selection process. This will act as if you normally
404double-clicked the image to display it, and will toggle the selection
405twice, resulting in no change.
