A trigger is an event (e.g. hot key) that causes the macro to run.
Active triggers - select what trigger types are enabled when QM is in "enabled" state (blue tray icon) and when in "disabled" state (gray icon). Triggers of "QM events" type are always enabled.
Mouse sensitivity - changes sensitivity of mouse triggers. To increase sensitivity (decrease required amplitude and speed), move the thumb to the right.
System - open the system Mouse Properties dialog. Recommended mouse pointer and hardware settings: average or high speed, no acceleration or low acceleration, average or high sample rate.
Use low-level hooks - makes keyboard and/or mouse triggers more powerful and reliable. The low-level keyboard hook allows you to use hot keys used by Windows, etc. Low level hooks also make triggers to work in console windows in Windows Vista.
