I want to clear the Console tab in Chrome developer tools inside the Chrome browser. I know that their is an button for that but what's the shortcut keys for doing that?
Are their anywhere cheatsheet for chrome developer tool or chrome shortcuts?
You can use Ctrl + L to clear the chrome-dev-console.
The list of keyboard shortcuts for Chrome Developer Tools is at: http://code.google.com/chrome/devtools/docs/shortcuts.html.
For clearing the console log, press Ctrl-L. Unfortunately, it appears the log needs to be in focus (clicked on) for the keyboard command to work.
Keyboard shortcuts
Ctrl + L or Cmd + L
Command line
clear()
Here's a cheatsheet for more shortcut keys: http://anti-code.com/devtools-cheatsheet/
I do not know why, but on my Mac (OS X El Capitan v10, Google Chrome v40) shortcuts mentioned above Cmd+L do NOT clear the Console log.
But Cmd + k perfectly works !!! Before using this shortcut make sure that the console is active!
So my solution for Macs is: Cmd + k !!!
It is Ctrl + Shift + L for Firefox console.
