New action/keybind: "Seek to cursor and play"

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

Sometimes I place the cursor somewhere on the timeline and want to preview a little bit of video from there, and afterwards I may have decided that that was a good spot to set a mark or cut or whatever. But when I pause, the cursor moves to the advanced playhead—I lose the cursor position.

A couple of actions/keybinds could fix this:

• Seek to cursor and play - allows to review footage from a position multiple times, like a loop
• Pause and seek to cursor - often times this is actually the behavior I want as default

Another way to formulate this is to distinguish the current behavior as "Continue playing", and adding a new behavior called "Play from cursor/last position".

Thank you so much :)
