how to pause video clip to allow for free response text

[LEFT] [/LEFT]
[LEFT]Hello[/LEFT]
[LEFT]I had a question regarding the DirectRT program. [/LEFT]
[LEFT]Throughout the course of my experiment, I would like to present the participant with a video clip. [/LEFT]
[LEFT]While watching, I would like them to be able to pause the movie at any time, type in a "description" of some sort in a response box , and afterwards be able to continue watching the clip from where it left off. (in short = pausing)

[/LEFT]
[LEFT]I want to allow the [B]participant[/B] to press a key, which will temporarily pause the video file, and allow some sort of free-response text space for them to describe what they were feeling at that second (for example). [/LEFT]
[LEFT]Does anyone know how this can be done?[/LEFT]

[LEFT]Thanks so much, [/LEFT]
