Seekvideo to selected subtitle, but not opposite (switch to subtitle where i stopped playback)

[slrslr]

Hello,

i have clicked the subtitle (is highlighted in green), i edit it, it is still green, and i click Play the video. After 1 minute of playback i want to adjust the subtitle at current playback time, but how to find it, i still see old subtitles from 1 minute back and I am unable to find the menu entry and keyboard shortcut that would do it.
