vim の help の写し (SC100: Text Editing with Vim 受験記)

SC100: Text Editing with Vim を受けるために Vim の勉強をしてみました。結果は 83/100 で合格。結構いろいろとコマンドを覚えましたがかなり基礎的な vim のコマンドに加え次のような項目のごく簡単な使い方が理解できていれば力業で解ける気がしました。

• Windows
• Visual Mode / Visual Block Mode
• vimdiff (vim -d or :diffsplit)
• vimrc (必要に応じて help ファイルを見ればよい？)

注意点としては :help コマンドが使えないこと。ディスク上 (/usr/share/vim/vim91/doc など) に help のファイルはあるのでわからない場合はそこを参照することになります。

以下は vim の勉強のために無駄に :help を写経した残骸です。SC100 対策としてはここまで覚える必要はありませんでした。。
