Disable F1 on xfce terminal

Copied from Function Key Binding in XFCE and the FAQ:

1. Run xfce4-appearance-settings.
2. Click Settings tab.
3. Check Enable editable accelerators.
4. Click Close.
5. Open an xfce terminal.
6. Click the Help menu.
7. Hover over Contents (do not click).
8. Press the Del key to delete the accelerator.

F1 disappears from the menu item.

The fullscreen accelerator, F11, can be removed similarly:

1. Click View
2. Hover over Fullscreen.
3. Press Del.

Pressing any other key than Del reassigns the accelerator key to the key that was pressed.

At least for xfce-terminal of version 0.8.6 or higher there is an option within preferences, where this can be easily set.

Yeah, this may seem obvious. I posted this in order for people landing here from their favourite search engine to know there is much easier way to solve the problem now.

on xubuntu 12.04 with xfce4-terminal 0.6.1 (Xfce 4.10) I've resolved adding:

in ~/.config/xfce4/terminal/accels.scm

(gtk_accel_path "<Actions>/terminal-window/fullscreen" "")
(gtk_accel_path "<Actions>/terminal-window/contents" "")

and in ~/.config/xfce4/terminal/terminalrc

AccelFullscreen=
AccelContents=

so both F1 help/contens and F11 fullscreen are disabled
