The Change Profile action allows you to load a completely different VoiceWarrior profile (*.vcm). This will cause the current profile to be unloaded, but global commands will remain.
An example usage might be to setup GLOBAL commands that load your most common application/game profiles. "Load Minecraft" could Launch the Minecraft game and then load the Minecraft profile. While in Minecraft, you could say "Load Desktop" to switch to the desktop (Windows button + D), and continue with desktop related commands.
An even better use case might be for Virtual Reality headset users. It is convenient to switch profiles as you change applications without removing your headset.
This command provides great flexibility for supporting many types of usages.
