Apple Script to reload current tab in chrome:
tell application "Google Chrome" reload active tab of window 1 end tell
I bind it to a global shortcut in Alfred (this requires wrapping in
alfred_script callback. Also I'm using Canary for previewing site in development so application name is adjusted:
on alfred_script(q) tell application "Google Chrome Canary" reload active tab of window 1 end tell end alfred_script
If you want reloading automatically on file changes there's LiveReload and plenty alternatives software.
