**ShowPlay Reference Manual, Chapter 1 (Introduction): stimuluscommands** ===== stimuluscommands -- ===== Stimulus commands are control operations that you might want to embed into your \l[STIMULUS;stimulus list]. They include things like changing the \l[font;font], \l[textcolor;text] or \l[backcolor;screen color], \l[erase;erasing] the screen, \l[bdraw;drawing] a shape, or \l[rwait;waiting] for a response. In the stimulus table, you specify a time when the command should be executed but no duration (there are usually other parameters as well -- see below). **See Also:**\\ [[jvs:cigal|CIGAL Home]], [[jvs:cigal:manual|CIGAL Manual]], [[jvs:cigal:showplay|ShowPlay Home]], [[jvs:cigal:showplay:manual|ShowPlay Manual]], [[jvs:cigal:showplay:manual:chapter1|Introduction List]], [[jvs:cigal:showplay:manual:help|Manual Help]]
