Shortcut/app to capture only the content of a window in a screenshot? System Software Overview:

  System Version:   macOS 10.13.6 (17G3025)
  Kernel Version:   Darwin 17.7.0


I would like to capture only the content of a window, without the menu. In other words, I would like to capture this:



instead than this:



I can use Cmd+Ctrl+Shift+4 and then resize the capture area to just the contents of the window, but that's not very convenient...isn't there a shortcut which doesn't involve selecting areas with the mouse?
I'm not sure how convenient this would be for your workflow...


Switch to fullscreen.
From the View menu, uncheck "Always show toolbar in full screen"
Use  Cmd ⌘   Shift ⇧   4  then tap the spacebar &amp; click in the window
This will [as always] take a snap of the entire window - but in this case it will leave out the toolbar entirely.
Scrollbars will hide or show depending on your setting in System Prefs > General
