I can't find a feature that allows me to open up a slide to fit the whole screen
Almost any PDF viewer have in the view menu a "Full Screen Mode", "Presentation mode" or something similar,as well as shortcuts as
Ctrl+L (Acrobat Reader),
F5 (Evince) or
Crtl+Shift+P (Okular).Just search in the menu.
But if you want start in this mode to avoid delays in front of the audience, you can use the option
pdfpagemode=FullScreen of the
hyperref package (already loaded by the document class):
This way, assuming that you open the PDF with Acrobat Reader (e.g.:
acroread file.pdf) it should be showed in the whole screen without
Ctrl+L, although this and others viewers as
okular will ask for confirmation the first time. Others as
xpdf simply ignore this option. Others as
evince simply do the job. Others as
impressive (really a presentation tool, not a simple pdf viewer) show any PDF in full screen mode, with or without this option.
and then click through my presentation with the space bar.
This is the usual behavior in presentation mode with any PDF viewer (space bar = next page).
