Suggestion: Add Text Search Box In Script Help Window

I want to suggest adding a text search box at the top right of the Script Help window or add support for Control + F for text search.

If you decide to buy, don't forget to tell them that Mel (MovieMaker) sent you. They have been very good to me, and I want them to know that I appreciate it by spreading the word. Don't expect for...

Servo Motors Disengaged

@DJ Just a heads up. I just went through the servos in my kit and found three of the 4 standard servos did not function correctly. They whined when plugged in. After closer examination, I found that the servo motors had shifted down in the casing during shipping causing the motor gear to disengage from the gear stack. I pushed them back into place...
