The :keeppatterns modifier runs an Ex command — typically :s, :g, or :v — without modifying @/ (the last search pattern) or the command history.

:lockmarks
Many Ex commands silently adjust or delete marks as a side effect of modifying buffer content.
:call feedkeys("iHello\<Esc>", 'n')
The feedkeys() function injects keystrokes into Vim's input buffer as if the user typed them.
:call timer_start(1000, {-> execute('echo "done"')})
Vim's timerstart() function lets you schedule code to run after a specified delay in milliseconds.
:doautocmd User MyEvent
Vim's User event type lets you define custom events that fire on demand.
:execute 'normal! ' . count . 'j'
The :execute command evaluates a string as an Ex command, enabling dynamic command construction.
