The toolbar, palettes and files

The toolbar holds dozens of tools, but they are grouped to save space: a small triangle in the corner of a button means that more tools are hidden under it. To open a group, hold the button or right-click it; each group has one Latin letter (for example M – selection, L – lasso, B – brush, T – text), and pressing the letter with Shift cycles through the tools of the group. The chosen tool stays chosen after the work is done, so it is a good habit to return to a harmless tool such as Hand to avoid spoiling the picture by accident. Palettes are extra windows such as Layers, Channels, History, Navigator and Info; they are shown by ticking the item in the Window menu and hidden by unticking it. To change the zoom use Ctrl+“+” and Ctrl+“–”, Ctrl+0 to fit the picture on the screen and Ctrl+1 for 100%; even when another tool is active, holding the space bar lets you move the picture like the Hand tool. In the Navigator palette a red frame shows the part of the picture visible on the screen and can be dragged to move the view.
