replace word with yanked word

in visual mode, select the word that should be replaced, press p to paste in-place.
The problem is, you cannot repeat this operation by .. The paste buffer is overwritten by the replaced word. So it pastes the replaced word, not the original word you copied from somewhere else.
any better solution?

Plugins: surround

ysiw: add surrounding symbol. ‘yank surround’ is weird since it’s not yanking anything, and the command’s rather long, so I remapped ys to s
ds: delete surrounding symbol
cs: change surrounding symbol

Coding

Go to pair brackets () []

%

Indentation

>> and <<, can be remapped to <Tab> and <S-Tab>
= is smart indent, but not very useful for bracket-less language like python

Plugin: mini.comment

gc: toggle comment

Plugin: wrapping

yow, toggle softwrap and hardwrap

Rather useless keys that should be remapped

, and ;: repeat f, t movement - I can first jump back more before using the f, t movement, also, n and N movements through searching are more direct
s: delete current word and go to insert mode - similar to r and c. Should be remapped for surround plugin
m: bookmark the position - too hard to use, search and '' are simpler

Markdown

za: fold toggle, remmaped to z
1z=: fix the spelling of the current word, remapped to ,

Plugin: Smart yank

share copied content between vim and system keyboards, does this automatically when the intent is clear.

Plugin: vim-exchange

tips on paste

when the yanked content contains newline at the end, when you paste the content, vim will not paste at the cursor, instead, vim pastes the content at the line below the cursor. If you want to paste inline, don’t use DD to yank the line, use d$ instead.
