How to select all keyframes from left or right having current frame as pivot? I've been doing some animation with tons of keyframes and when I need to apply some change, I spend a lot of time selecting keyframes on dopesheet (pressing B, select all I want and perform change)

but this is very time consuming, I was hoping for some shortcut where I could select all keyframes from the left or right based on the current frame

script would work too,  I have to clue to start it by the way

any tips are welcome, thanks
Right click the key frame that should be the first of those you need selected and the hold Ctrl and either click the [ key for all keyframes on the left or the ] for all on the right (while Ctrl is held).
