Some commands in terminal can produce a lot of output (for example, ./configure of Qt5). It is very boring to spend my time by selecting it by mouse. Can you add menu item or hotkey `Select all`? P.S. I know about pipes but I'm lazy :D Reproducible: Always
I'm glad to tell you that this feature has been available since KDE SC 4.8 :) I know Debian is still at KDE SC 4.7.4. So either push the Debian KDE team to ship KDE SC 4.8, or compile konsole yourself(The good news is you can compile the latest code of konsole as long as you have KDE SC 4.7+).
Thanks, I'll push the maintaners :D
