I would like that a video starting from/to a certain position. This event
should released by keyboard-trigger. It should play so for a
long time to the key is released. Unfortunately there is not a
trigger "key press down".
Does someone have an idea, how I can solve this problem in Opus? In
Mediator there is such a trigger, I would like the program with Opus
to however rather realize.

have you looked at triggers---advanced-----keypress?? or is this not suitable for what you are trying to do???

there is also a script test for key pressed

Quote:

IsKeyPressed()

Syntax:

IsKeyPressed( Key1, Key2, … )

Return:

true if a specified key is pressed down. Otherwise, false.

Parameters:

Key1, Key2, – a single character string representing a text key (e.g. a, b, c ) or one of special keys listed below. More than one Key can be included within each function. Each Key should be separated by a comma. This parameter is required.

Special Keys:

One or more of the following strings: "Up", "Down", "Left" or "Right", representing the keyboard arrow keys. As well as one or more of the following: "Control", "Shift","Alt", "Backspace","Enter", "Caps","Pause", "Tab","Escape", "PageUp","PageDown", "End","Home", "Print","Insert", "Delete","Help", "LeftWin","RightWin", "Add","Multiply", "Subract", "Decimal", "Divide", "F1", "F2", "F3", "F4", "F5", "F6", "F7", "F8", "F9", "F10", "F11", "F12", "F13", "F14", "F15", "F16", "F17", "F18", "F19", "F20", "F21", "F22", "F23", "F24" , "Numpad0", "Numpad1", "Numpad2", "Numpad3", "Numpad4", "Numpad5", "Numpad6", "Numpad7", "Numpad8", "Numpad9", "NumLock"

Remarks:

This function will return true when a specified key is being held down. This function is useful for programming keys to perform different actions in your script.

two other things to look at ....... custom actions/triggers............. and the event handler in script [RegisterEventHandler( EventName, EventFunction )]

hope this helps

I tried a quick test.
I added an action to a page

using Trigger-----advanced-----key pressed(SPACE)

this trigger was used to show an image

then Trigger----advanced------key released (SPACE)

[note to activate a key, put the cursor inside the 'specific key' box and then press the key you want to use as the trigger]

this trigger was used to hide the image.

so when you press the space bar, the image appears and remains as long as the space bar is pressed, when you release the space bar, the image is hidden.
You should be able to use this, or a similar method to play/stop a video

Thank you very much for the fast answer. I will try the solution ways equally today.

Maybe the attached IMP file will help. I've applied the action that if you press the space-bar key the video plays, if you release it will stop or pause depending what you set. I think this would be the same as the user holding the key down?

Hello leo and sandyn, you have right, that went actually very simply. I can explain however why it did not function with me.

If I for example that "a" key press, should play the video from an certain position. Therefore I determined the starts and endposition in the video-action under Time. If I this do works it no longer correctly.

Each key should play a certain part of the video. Is that possible? With the mouse-trigger "left mouse down" work that, I however the keyboard-trigger as a triggers.

Can you help?

There may be some access to state of keys being pressed... check out RegisterEventHandler for what that offers. You may need to construct it with some loop or other means to keep 'polling' some variable. "IsPlaying()" may also be a way to verify in combination with key presses.
