*'timeout'* *'to'* *'notimeout'* *'noto'*
'timeout' 'to' boolean (default on)
global
This option and 'timeoutlen' determine the behavior when part of a
mapped key sequence has been received. For example, if <c-f> is
pressed and 'timeout' is set, Nvim will wait 'timeoutlen' milliseconds
for any key that can follow <c-f> in a mapping.
*'ttimeout'* *'nottimeout'*
'ttimeout' boolean (default off)
global
{not in Vi}
These two options together determine the behavior when part of a
mapped key sequence or keyboard code has been received:
'timeout' 'ttimeout' action ~
off off do not time out
on on or off time out on :mappings and key codes
off on time out on key codes
If both options are off, Vim will wait until either the complete
mapping or key sequence has been received, or it is clear that there
is no mapping or key sequence for the received characters. For
example: if you have mapped "vl" and Vim has received 'v', the next
character is needed to see if the 'v' is followed by an 'l'.
When one of the options is on, Vim will wait for about 1 second for
the next character to arrive. After that the already received
characters are interpreted as single characters. The waiting time can
be changed with the 'timeoutlen' option.
On slow terminals or very busy systems timing out may cause
malfunctioning cursor keys. If both options are off, Vim waits
forever after an entered <Esc> if there are key codes that start
with <Esc>. You will have to type <Esc> twice. If you do not have
problems with key codes, but would like to have :mapped key
sequences not timing out in 1 second, set the 'ttimeout' option and
reset the 'timeout' option.
This option and 'ttimeoutlen' determine the behavior when part of a
key code sequence has been received by the terminal UI. For example,
if the \x1b byte is received and 'ttimeout' is set, Nvim will wait
'ttimeoutlen' milliseconds for the terminal to complete a byte
sequence that represents a key that starts with \x1b.
*'timeoutlen'* *'tm'*
'timeoutlen' 'tm' number (default 1000)
global
The time in milliseconds that is waited for a mapped sequence to
complete.
{not in all versions of Vi}
*'ttimeoutlen'* *'ttm'*
'ttimeoutlen' 'ttm' number (default -1)
global
{not in Vi}
The time in milliseconds that is waited for a key code or mapped key
sequence to complete. Also used for CTRL-\ CTRL-N and CTRL-\ CTRL-G
The time in milliseconds that is waited for a key code
sequence to complete. Also used for CTRL-\ CTRL-N and CTRL-\ CTRL-G
when part of a command has been typed.
Normally only 'timeoutlen' is used and 'ttimeoutlen' is -1. When a
different timeout value for key codes is desired set 'ttimeoutlen' to
a non-negative number.
ttimeoutlen mapping delay key code delay ~
< 0 'timeoutlen' 'timeoutlen'
>= 0 'timeoutlen' 'ttimeoutlen'
The timeout only happens when the 'timeout' and 'ttimeout' options
tell so. A useful setting would be >
:set timeout timeoutlen=3000 ttimeoutlen=100
< (time out on mapping after three seconds, time out on key codes after
a tenth of a second).
*'title'* *'notitle'*
'title' boolean (default off, on when title can be restored)
