When you type at insert mode, did you ever yank text at other place, and paste at current position?
Normally you need to type <ESC> to back normal mode, then go to yank the wanted text, then press g;pa to jump back,
paste and reenter the insert mode.
This pattern is so common to me. so I have created this plugin. With this plugin, you map a expr key to WaitYank#Paste, then when you yank, vim
will auto jump back, paste and reenter insert, save the 4 g;pa key and keep you focusing on input.
