Lmao when i 1st played doctor today (i played dbr since 2019 but i didnt know the donation unlocks the doctor so i just bought halloween) 3 of the people dc'd and the last one after everybody left gave up..
1st u cant grab 2nd m2 is right mouse button so u just press it to get into shock mode, then press again to exit it. While in shock mode press m1 to shock instead of hit
You press right click to get into shock mode, then you use left click to shock survivors which will briefly make them unable to vault. Then, press right click again to go into attacking mode so you can hit survivors.
