Not only arrow keys. Don't forget the search capability, and commands
such as (normal) 1234G or (ex-command) :1234 to go directly to a known
line number. Also 75% to go to a given percentage of the file's length.
I have one very large file, the Unihan database, a copy of a text file
from the Unicode site, each line of which includes three tab-separated
fields, namely, Unicode codepoint, key name (there are quite a number of
possible keys, and usually several are present on successive lines for
each codepoint) and key value. You could equate it to as many
Dictionaries (in the Vim sense) as there are Unified CJK Characters.
Quite bulky. Well, I never go very far into it with just up-and-down
arrowing (let's say to different keys for a given codepoint, at most two
or rarely three screen heights) but I use regexp searching quite a lot,
either by codepoint or by key+value: for instance, I could search for
codepoints whose meaning includes the word "big", for characters made
from Radical 140 "grass" plus five additional strokes, for words which
can be read er4 in Mandarin or futatsu in Japanese-Kun, and so on and so
forth.
Best regards,
Tony.
