QuickEdit Mode in cmd.exe
I have just found out that I didn’t need to use the mouse to copy and paste to / from a cmd.exe Window.
With your hands on the keyboard:
Windows+r, c, m, d, enter, alt+space, p, alt+q, enter, alt+s, enter.
For those less fond of the keyboard: start cmd.exe, right click on the titlebar, and select properties. In the first tab enable ‘QuickEdit mode’, and click OK. You will then be prompted if you want to apply the changes for this session only or to save for all future sessions.
Now you have a quick edit mode enabled. You can select text with the left mouse button, and paste it with the right mouse button. Without quick edit mode to copy text I had to take the mouse, right click on the titlebar, click, edit > mark. To paste text I had to click edit > paste.
