Reload all of the current window's tabs
Reload all of the current window's tabs by pressing the icon or using the Ctrl+Shift+E shortcut.
You can change the default shortcut to something else by opening the extensions page (chrome://extensions/) and clicking the keyboard shortcuts link in the bottom right corner of the page. From there, find the Reload tabs extension and enter a keyboard shortcut of your choosing.
