develop Haskell code with vim and haskelmode plugin

Question

I have a silly question, I'm sure, I use vim with haskell-mode plugin to develop on haskell but I'm not sure how to enable the keys combination define on the haskellmode -vim, for example:

|_ct| create |tags| file

|_si| show info for id under cursor

|_t| show type for id under cursor

|_T| insert type declaration for id under cursor |balloon| show type for id under mouse pointer

|_?| browse Haddock entry for id under cursor

|_?1| search Hoogle for id under cursor

|_?2| search Hayoo! for id under cursor

how to type a command on vim that start with '_' (I know there said that this represent cursor and than I suppose that I just have to type 'si' for that field but nothing is happened) on which mode have to type it, I suppose on normal mode. I work on Mac but the same problem I have on linux.

Thanks Sorin.

From the documentation:

Finally, the mappings actually use <LocalLeader> behind the scenes, so if
you have to, you can redefine maplocalleader to something other than '_'.
Just remember that the docs still refer to mappings starting with '_', to
avoid confusing the majority of users!-)

So you must press _, then C, then T in rapid succession to create a tags file for your project.

Unless you have set your <LocalLeader> to something other than _.
