Here's how to access the procedures mentioned above. I don't have Windows 95 at hand, so possibly it is limited in these capabilities. So try them, maybe Win95 does have it after all? [Windows 98 or Millennium or XP are much more solid products than Win95, so feel free to upgrade. Unfortunately, each new version of Windows moves farther away from the DOS world.]
To access the Copy/Paste/Select All features, right-click on the opened DOS window's top bar, the blue "drag" bar. The Edit item has a submenu with Mark and Copy and the other options are disabled. In order to get Copy enabled you must first Mark a block of text.
In order to find the QuickEdit checkbox, right-click on the DOS icon on the desktop. Is it shown there on the Properties option, Misc tab?
Personally, I'd recommend using the first method and avoiding messing with the QuickEdit mode.
