The "timeout=0" starts the boot process without delay. Set it to a
higher number.

I run with hiddenmenu commented out and timeout=8 and have no problems.
Uncommented and "hit any key" displayed and works fine as well.
Do you have a USB keyboard?

I think that might be the correct question to ask. ;) I have had similar
problems, the fix was to `enable USB devices while booting' in the BIOS.
But since you could do this earlier, not sure its a similar problem but
worth a try.

I have run into this when using a USB keyboard and legacy support is
disabled in the BIOS. Grub is not seeing any keystrokes from the
keyboard. If this is the case with your system, you will need to
change the BIOS settings, or plug in a PS2 keyboard.

You do not need legacy support for the PS2 keyboard. (The round
plug.) Legacy support makes a USB keyboard look like a PS2 keyboard
to the system. The fact that you had a USB keyboard when you
installed should not make a difference.

What is the value of timeout in grub.conf?

Wikipedia seems to think it's the other way around:
Legacy support
The term legacy support is often used with reference to obsolete or
legacy computer hardware, whether peripherals or core components.
Operating systems with "legacy support" can detect and use legacy
hardware.

And, if I may add, if I can't access the boot menu, it can't have much
to do with Fedora

BIOS USB legacy support is a bit different. It is using the BIOS to
support legacy programs that expect a PS/2 keyboard/mouse when you
have a USB keyboard/mouse. You do not need it when you are using a
PS/2 keyboard and mouse. A serial mouse is a completely different
story, but not too many people have them... :)

Here is an interesting problem that links with this thread.
I have one machine that is around 6 years old on which I have f11 working perfectly well (previously it was f10 ) but one issue still remains. Plugged into a rear usb port is the sender for a radio mouse. The mouse has newish batteries and works fine with everything running and powered up.
However if i power the machine off, and then restart the machine (Dell Dimension 2400 desktop) the screen is unresponsive to the mouse movement or buttons unless I unplug the radio sender that is plugged into the usb port, and reconnect it. Immediately the mouse then works as normal!! I seem to remember that this was the case when I installed f11 also - in that I booted the install media and the mouse failed to respond at the graphical install stage until I unplugged and replugged the radio sender. Is it likely that this is a BIOS setting issue as well?

Less likely, better check your /var/log/messages file for something related.

Well I just switched off the machine in question and booted from a cold start.
The problem that was there consistently in the past seems to have gone away.
The mouse now gets recognised immediately that the kdm greeter starts.
I presume that a fix was done in an update at some point - but due the problem
being there I had only rebooted without powering off and back on for a month or
two.... however certainly it was as I reported until a few weeks ago.

It is often a good idea to reboot after important updates...

Of course and indeed I HAD rebooted after each set of updates - the difference is
that if you power off and reboot then there is hardware resetting that is
different to rebooting but leaving the power on!
Today was the first time I shutdown AND powered off. Then started from cold.
This has a different effect to simply asking for a re-boot but leaving the power
running during the shutdown and subsequent re-boot.

Please explain what do you mean by 'different effect' and how is the hw
reset by rebooting vs cold boot
