  • LTSpice IV: Simulation Run Hotkey

    For some odd reason, Linear Tech’s LTSpice IV simulator has a hotkey to stop a simulation (Ctrl-H), but not one to start the run.

    • Control Panel
    • Drafting Options

    • Back out of everything
    LTSPice Run key binding
    LTSPice Run key binding

    Done!
