How to use the testtrigger function？

Today I test the testtrigger(shift+ctrl+F12) function but failing. I input some words into the testtrigger window and click the confirm button . The words that I input displayed in the output window immediately. But the trigger which matched these words doesn't fire . Only some simple words like you drink some water . Why doesn't it fire?

What trigger are you trying to test and what are you putting in the window?

I usually put a blank line (Ctrl+Enter) before and after the testing text, so it appears to come on a new line.

Thanks，Nick. I use your way to test it and succeed . Now it is working correctly .
