But as your mail left a few things open (Select or execute? Normal
keys or keys with modifier? Single-letter-keys or strings?), the
discussion about this would have had to be continued anyway. :-)
I prefer to execute it when a shortcut key is pressed. Why not?
Because then it would not be possible to edit menu items blindly.
For example, I could not blindly add boot parameters to the Linux
kernel (runlevel, root=<whatever>, etc.) to override the default
settings (which I do, indeed, e.g. for my SCSI testing machine
which varying disks with varying partition layout connected, so that
fixed menu items don't help).

I think the best choice to do it is to bind a key like C-p to add parameters to the entry. Then theese parameters will be accessible as $1, $2, ... ($0 is a label of menu entry)

Accessible to whom or what?

To the scripts

My scenario would be something like this:

1. Hit 's' to enter select-menu-entry-by-name mode (optional)
2. Type "linux" and hit [Return] to select (not execute) menu item
  "Linux 2.4"
3. Hit 'e' to edit. Now the cursor could be at the end of the line
  by default, so that I just need to type for example:
4. " root=/dev/sdf" [Return]
5. Hit [Return] again (or 'b') to boot.

The problem with this scenario is the determination of line by default especially for scripts. You can have a script that launches different kernels depending on condition or it can use function. Which line is the default one?
