Also, try the "X" hotkey (Next Harmonic Family). I immediately use it on just about every spectra. Picks out v-belt frequencies with ease. Helpful when you think you see a bad bearing, but don't know the actual bearing info, or don't have it setup in your fault frequencies ("L" key).
The "C' key changes the cursor from "single, harmoic, sideband" quickly. Use the "Z" and "A" keys before using the "C" key to switch to sidebands.
When looking at just the spectra data, I use the "S" key to quickly peak at the waveform, then hit the "F" key to go back to the spectra.
Use the "L" and "Alt-L" to look at your fault frequencies you've setup.
Use the "Q" key to switch frequency units (I'm order based most of the time).
All of these hotkeys go back to the MS-DOS days of CSI's MasterTrend software, when there was no mouse to move around with. Hotkeys are great for analysis, much more efficient than using the mouse or touch pad.
