There are always displayed two toolbars, one main and one mode-dependent. The main one is always
on top of the whole window and does not change; the latter can appear either right under it (default
position), or in the bottom on top of statusbar. Since mode-dependent toolbars are described in
their mode topics, this part will focus on main toolbar.
First group of buttons
works indeed the same way as in most programs and as you would expect from their icons - Open,
Save and Save as. Their respective keyboard shortcuts are
Ctrl ,
Ctrl and none. If you want,
you can switch in options on or off (default) additional button for closing the program,
which appears as first in this group.
Right-clicking the open button opens a
menu with "special files" - built-in pictures for testing. They can be also accessed by entering
their name in form "about:something" in open dialog. As of version 4.7, the following are
included:
The second
group's buttons affect the overall display of edited picture, regardless on viewing mode. The two
small ones are for zooming; preferred and more powerful method is via keyboard
( , on numpad) and middle mouse
button, though. The only "normal" button here is for bringing up the background dialog
( ) - see topic Background.
Third group buttons change
the way picture is displayed, or in my personal terminology,
viewing mode. This has its own topic.

The next three
buttons switch editing modes:
Areas,
Pixels,
Moving
- on keyboard
,
and
. Each editing mode has its own topic - no further info here.
Two arrow buttons
invoke undo/redo. Shades have unlimited undo, which means you can always undo everything back to
the initial picture state. Still, if you work on a ridiculously low memory machine, you can
disable this behaviour by setting maximal undo level in options. Keyboard shortcuts are
Ctrl and
Alt for undo and
Ctrl and
Ctrl for redo.
The last group includes
button for options window
(Ctrl ) and help & about window.
You won't probably need these every so often.
