Presentation Mode is similar to the online players, because it updates the Stage only at the end of loops and at wait blocks. Thus, the following script will draw a line, which will flicker a little in the normal mode but will not in Presentation Mode:
when gf clicked forever clear pen up go to x: (0) y: (0) pen down go to x: (100) y: (100)
See Single Frame for more information.
Presentation Mode also lacks the glitches associated with the Java or Flash players. Before the advent of the Flash player, Presentation Mode (in Turbo Mode) was the fastest method of playing projects. For these reasons, many projects that are online encourage users to download and run in Presentation Mode. It is also where many projects are tested before uploading.
While in Presentation Mode, projects can not be edited. This is one of the purposes of the feature.

In the Flash Player, there is an full screen mode. If the enlarge screen button is shift-clicked, it goes into full screen, like Presentation Mode. The Flash Player allows projects to be played full screen online, and even in turbo mode.
BYOB Executable Files
In BYOB, when a project has been compiled to an EXE, it runs in Presentation Mode when opened. When presentation mode is exited, BYOB automatically closes.
