Switch automatically between normal and insert mode in vim -

i new vim , have installed oh-my-vim , learnt these keybindings googling:

jump forward word - w

jump forward word - b

jump end of sentence -

close current file without exiting - bd

undo u

execute shell command ! (bang)

of these typing shift + in normal mode allows me jump end of sentence , goes insert mode start typing after it. tried out shift + w , shift + b , shows similar behaviour of going insert mode start typing after use keybinding.

what equivalents these keybindings not using letter?

jump start of sentence - 0

redo ctrl + r

jump previous line - ``

hope clear in describing. thanks!

it's not entirely clear asking. shift+w , shift+b not automatically enter insert mode, instead go , forth on words (vs words).

if want enter insert mode, hit i. hit wi insert after word.

you mention 0, goes beginning of line. can hit i (shift+i) insert @ beginning of line. note inserts after initial whitespace on line, same hitting ^i. if want insert @ beginning of line, you'll need use 0i.
