If you look at :h f you'll see

|:lmap| mappings apply to {char}

(as in f{char})

Go to :h mapmode-l:

":lmap" defines a mapping that applies to:
...<snip>...
- the argument of the commands that accept a text character, such as "r" and "f"

So lmap <c-j> <space> ... note, though, that you may need to type Ctrl+^ before using any lmap mapping.

(You can also brute force it with :nnoremap f<c-j> f<space> and for F,t,T.)

If you look at :h f you'll see

|:lmap| mappings apply to {char}

(as in f{char})

Go to :h mapmode-l:

":lmap" defines a mapping that applies to:
...<snip>...
- the argument of the commands that accept a text character, such as "r" and "f"

So lmap <c-j> <space> ... note, though, that you may need to explicitly enable lmap mappings by typing Ctrl+^ while in Insert mode. Alternatively, ensure that 'iminsert' is set to 1.

(The docs are misleading about this, btw. What I'm reading is that this setting only applies to use of lmap mappings used in Insert mode. But a simple test reveals that it applies to the f family of Normal mode commands. Anyone have a different interpretation of :h 'imi' and :h mapmode-l? Am I insane?)

FYI: you can also solve your problem by brute forcing it with :nnoremap f<c-j> f<space> and for F,t,T.

If you look at :h f you'll see

|:lmap| mappings apply to {char}

Go to :h mapmode-l:

":lmap" defines a mapping that applies to:
- Insert mode
- Command-line mode
- when entering a search pattern
- the argument of the commands that accept a text character, such as "r" and "f"

So lmap <c-j> <space>?
