Fix laggy key presses ​

If key presses are slow or laggy, check the system configuration.

Halt and Catch Fire (2014 - 2017)

Ubuntu ​

On Ubuntu you can configure keyboard repeat interval and delay:

bash
gsettings set org.gnome.desktop.peripherals.keyboard repeat-interval 3
gsettings set org.gnome.desktop.peripherals.keyboard delay 150

GUI ​

Settings → Universal Access → Typing → Repeat Keys

Adjust the delay and speed.

KDE ​

On KDE you can open a window to change the 'Delay' and 'Rate':

bash
systemsettings5 kcm_keyboard

Mac ​

On Mac, if holding down a key does not repeat the command (a feature of Mac), you make a key repeat by running this once at the terminal:

bash
defaults write com.sublimetext.3 ApplePressAndHoldEnabled -bool false

X11 ​

On X11 based systems you can directly use xset:

bash
xset r rate <milliseconds_before_repeating> <repetitions_per_second>
