This might be a simple question for NERDTree users.
I'm trying to use NERDTree, and I found two ways to open files in NERDTree window, press <CR> as enter and double-click the file with the mouse (same as with pressing o).
I wanted to open new file in the window at vertical right side (keep original file opened), and finally I could customize NERDTreeCustomOpenArgs. However, the way to open files with double-click seems to be different, so I want to remap double-click to NERDTreeCustomOpen, not to NERDTree-o.
I've tried to map the double-click as shown here and here, but it has not worked for me.
