There, toggle Hide text when toolbar shows action alongside icon to prevent the action from showing the text. Select the action to the right, and click Change text. Then select the action ‘undo freehand stroke’ and drag it to the right.

Then, you can type in something in the left column to search for it. There are two toolbars, but we’ll add to the Main Toolbar. Go to Settings ‣ Configure Toolbars… menu item. You can also put these commands on the toolbar, so it’ll feel a little like SAI. You can use the Overview docker in Settings ‣ Dockers to quickly navigate over your image. Use the 1, 2 or 3 keys to reset the zoom, fit the zoom to page or fit the zoom to page width. You can use the + and - keys to zoom out and in, or use the Ctrl + shortcut. But you can also have more sophisticated rotation with the Shift + Space + drag or Shift + + drag shortcuts. There’s a couple of possibilities here: either the 4 and 6 keys, or the Ctrl + shortcuts for basic 15 degrees rotation left and right. Unlike SAI, these are tied to keyboard keys.
