Start video at text-cursor

[murezzda]

Is your feature request related to a problem? Please describe.
In conjunction with #97, it would be great if the player can be started from the current word at the cursor position. This would allow for rapid navigation inside the video via keyboard.

Describe the solution you'd like
If the user starts the video via the alt+k shortcut, the video starts from the current cursor position instead of the current video position.

Additional context
As this feature alters the behaviour of the alt+k shortcut significantly, it might be good to put an option in the option menu to enable/disable this behaviour. Alternatively, another shortcut could be introduced for this feature, but I think this might increase the complexity of the application too much.

Thanks @murezzda since we closed #97 and parked it for now, closing this one as well. We are looking to consolidate the component before adding new feature, but happy to revisit at a later stage
