Verbs in Vim
d => Delete c => Change (delete and enter insert mode)
=> Indent < => Outdent v => visual select y => Yank (copy) p => Paste
Using dw will delete a word, but using cw will delete the word and put you into insert mode. So you and replace a word "bob" with "hello" by using cw hello using . will then repeat that operation.
Nouns in Vim - Motions
w => word (forward by a word) b => back (back by a word) 2j => 2 lines down (repeats j twice)
If you are in the middle of a word you want to operate on then you will need to use text objects.
Nouns in Vim -- Text Objects
iw => "inner word" (works from anywhere in the word) it => "inner tag" (the content inside of an HTML tag) i" => "inner quotes" ip => "inner paragraph" as => a sentence
Nouns in Vim -- Parameterised Text Objects
f, F => "find" the next character (f forward | F backwards) t, T => "find /,? => Search (up to the next match)
Can the dot command repeat the change I am trying to make? If not then I am probably doing something wrong. Vim is a very expressive language, if I am unable to express my change in it, it is probably me not Vim.
Try to use text-objects over motions, i.e. movements between objects such as { [ ( " < e.t.c rather than motions.
