Key shortcuts

Did you know that ShaderToy GUI as well as it’s CodeMirror shader editor had many key-shortcuts ? Seems that most people ignore it (despite GUI ones pop-up as tool-tips… if you try).


  • Cmd = “microsoft” or “apple” key.
  • Ctrl  might be overridden by your browser.
  • Mac: replace Ctrl by Cmd, or sometime by Alt or Ctrl-Alt.

GUI key shortcuts

  • “Down”, “Cmd Down”:  resetTime
  • “Alt Up”, “Cmd Up”:       pauseTime

  • right menu:                   save or copy image
  • “Alt+r” :                          video record

  • “Ctrl S”, “Cmd S”:         Save shader
  • “Alt Enter”, “Cmd-Enter”: Compile shader
  • “F5” :                              refresh page ( indeed it’s a browser shortcut )

Editor key shortcuts

Editor GUI

“Alt F”:                                     Editor in FullScreen
“Alt Right”, “Cmd Right”:     Go to Right Tab
“Alt Left”, “Cmd Left”:          Go to Left Tab
“Alt -“, “Cmd -“:                     decrease FontSize
