yes, your custom keyboard shortcuts are kept in the file

.denemo-2.4.3/actions/Default.shortcuts

that set will be loaded on start up. You have to be careful editing the

You may need to know the name of a particular key-combination to set it
as a shortcut. You can do this without looking up the Gtk
documentation: if you press any key that is *not* a shortcut *twice* a
popup will appear telling which key you have pressed, naming it for
you. (You can go on to look at other key-combinations even those that
are already set as shortcuts by pressing them with that popup showing).

There is more though: Denemo has a Scheme command for setting a
shortcut to an action, for example executing this:

(d-AddKeybinding "Set0" "0")

in the Scheme window will set the Denemo command "Set0" to be invoked
by the key whose name is "0"

So you can create a set of lines like this, execute it and get the
keybindings all set in one go. You can then create a command to set
that set of keybindings (shortcuts) which you can invoke via a
keypress.
For examples of this look at the script for the commands in the 
Main Menu ▶ _Input ▶ PC Keyboard menu, e.g.

Command: Note Names Move Cursor
Changes the shortcuts for note names a, b, c, d, e, f, g so that they
move the cursor to the nearest note of that name.
Location: Main Menu ▶ _Input ▶ PC Keyboard
Internal Name: NoteNamesMove

You may wish to use this approach so that you can switch quickly
between using the keyboard for different types of task - e.g. entering
note names and entering durations (or adding ornaments etc.)

Having a different set of shortcuts for the different activities would
avoid the problem that can arise when almost every key invokes some
command and any mis-typing will cause something to happen which may be
difficult to undo. It can also help in being able to re-use easy to get
at keys (such as the space bar) for most used actions when doing some
particular sort of editing task.
