You can try turning down the command weight and/or turning up the minimum confidence level.
These settings can be found by clicking
, and clicking the "Recognition" tab.
I recommend enabling "Show Confidence Level"(By checking the box next to "Minimum Confidence Level"), so you can get a feel for which value(s) may be appropriate.
Minimum confidence level can also be overridden for specific commands in the "Add/Edit a Command" window(useful if you experience certain commands getting triggered accidentally more often than others), or for specific profiles.
To set the minimum confidence level for a profile, click
, then
, and check "Override global minimum confidence level" in the "Profile General" tab.
