## Controls

You can use the following controls while dspdfviewer is running.

Note that mouse-clicks are subject to pointer position if the hyperlink support is enabled. If your mouse cursor changes to a hand, it will follow the link you are hovering on a click.

Keyboard: ?, F1 | Display quick-help (most important key bindings)
Keyboard: Spacebar, Page Down / Mouse: Left-Click, Wheel Down | Go one page forward Additional keyboard aliases: Down, Right, Return, Enter, N, F
Keyboard: Backspace, Page Up / Mouse: Right-Click, Wheel Up | Go one page backward Additional keyboard aliases: Up, Left, P
Keyboard: B, . (period) | Toggle blanking of the audience screen
Keyboard: G | Go to specific page (a number entry window will pop up) Note that the this counts PDF pages, so a single slide having 6 unmasking steps will be 7 PDF pages long, including the initial near-blank page.
Keyboard: Home, H | Go to the first page and reset the clocks to zero.

Use this if you want the clocks to stop at zero, use the G (goto) function to page 1 if you want to them to keep running.

Note that the Home key may be called "Pos 1" on some keyboards.

Keyboard: Escape, Q | Quit dspdfviewer.
Keyboard: S, F12 | Switch primary and secondary screens Use this if the audience sees your ’note’ side with the clocks and you see the actual presentation on your screen. If you just want to see the main presentation (for example, because the projector is behind you), use T.
Keyboard: T | Switch secondary screen’s function Use this if you want to see the audience side on your screen, without showing the notes to the audience. Pressing the button again will switch back to normal operation.
Keyboard: D | Switch duplication of the audience’s screen Use this if you want to see the audience side and the notes on your screen (so the full presentation), leaving the audience’s screen untouched. Pressing the button again will switch back to split mode.
