I assume you can do that with tmux regardless of the terminal being used.
According to this cheat-sheet, you need to:

1. Start or attach to a tmux session with tmux or tmux a
2. Switch tmux to vim-mode: tmux setw -g mode-keys vi
3. (Optional) Save the setw -g mode-keys vi part in the ~/.tmux.conf config file
4. Open tmux in copy mode by typing Ctrl+b followed by [ key
5. Press Space to start selection, then move to the begining of output by pressing gg, and then copy into the tmux buffer with Enter
6. You can paste the contents of the buffer by pressing Ctrl+b followed by ]

umm.. good workaround idea .. but it really needs something more simple and intuitive as a permanent solution like:
ctrl+a or right click > select all and then copy (ctrl+c or ctrl+shift+c)

...after all it is self proclaimed a modern-age terminal

Once you set this up, this is really simple. Alternatively, you can select everything by dragging the selection to the top of the terminal and then copying everything by either right-clicking or typing Ctrl+Shift+C

the CTRL+SHIFT+A hotkey(added in 247cf6f) is not shown in the HOTKEYS settings. Could you please add it there as well?
