Remap NERDTree up and down keys

[FloDuno]

Hi!
While trying to remap some keys in NERDTree I stumbled upon this ticket stating there’s no way to remap Tree-selectNext & Tree-selectPrevious actions without forking this project.

I decided to clone the project and saw that in the registerCommands() function you don’t assign a vim variable to those actions.

I tried to change

registerCommand("j", NerdAction.ToIj("Tree-selectNext"))
registerCommand("k", NerdAction.ToIj("Tree-selectPrevious"))

to

registerCommand("NERDTreeMenuDown","j", NerdAction.ToIj("Tree-selectNext"))
registerCommand("NERDTreeMenuUp","k", NerdAction.ToIj("Tree-selectPrevious"))

and I can now change those keys in my .ideavimrc.

Would you be interested in a PR for this modification? Or is there a reason I did not see to not make this mapping customizable?

How does this work with NERDTree in Vim? Looking at the docs, I don't see any special NERDTree mappings for up/down, so I assume it's just an existing mapping for Normal mode for j and k?

I’m sorry I did not reply directly to you so maybe you could not see my answer earlier. But here it is #1136 (comment)

I found this in the NERDTree doc https://github.com/preservim/nerdtree/blob/9b465acb2745beb988eff3c1e4aa75f349738230/doc/NERDTree.txt#L652 therefore the use of NERDTreeMenuDown & NERDTreeMenuUp as variables.
