One of the welcome features in Acrobat for PDF newbies is the intuitive 'How To...' panel that occupies its right-hand side of the Acrobat window. One of the best things about this panel is that it's now possible to view instructions without interfering with the manipulation of your document. In other words, you can put the instructions in the panel to use right away. Here are a few quick tips on making the most of the 'How To...' panel.
For instance, if you want either more room to read the instructions in the panel or a better view of the active document, grab the far left edge of the panel and drag it to re-size. Here are some keyboard shortcuts that should also help.
Shift+F4: Toggles the 'How To...' window.
Tab: Cycles forward between elements in the window.
Shift+Tab: Cycles backward between elements in the window.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
