This function mangles a generated form class to remove the Hold down "Control", or "Command"... messages from the help text. This is really a dirty hack awaiting a proper solution to Django ticket 9321.

This function can be useful for forms in the admin interface that use custom widgets. Basic usage:

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel

class MyAdmin(admin.ModelAdmin):
    form = remove_holddown(MyModelForm, ('field1', 'field2'))

def remove_holddown(form, fields):
    """This removes the unhelpful "Hold down the...." help texts for the
    specified fields for a form."""
    remove_message = unicode(_('Hold down "Control", or "Command" on a Mac, to select more than one.'))
    for field in fields:
        if field in form.base_fields:
            if form.base_fields[field].help_text:
                form.base_fields[field].help_text = form.base_fields[field].help_text.replace(remove_message, '').strip()
    return form

This is not going to work as that is too early in the code to remove the help text. You need to override the method formfield_for_manytomany():

from django.contrib import admin
from django.forms.widgets import CheckboxSelectMultiple, SelectMultiple

class SomeModelAdmin(admin.modelAdmin):
    def formfield_for_manytomany(self, db_field, request=None, **kwargs):
        """Ridiculous override just to get rid of the "Hold down" text"""
        form_field = super(SomeModelAdmin, self).formfield_for_manytomany(db_field, **kwargs)
        if ((isinstance(form_field.widget, SelectMultiple) and not
            isinstance(form_field.widget, CheckboxSelectMultiple))  # and
            #    isinstance(form_field.widget, BetterFilterWidget)):
            repl = unicode(_('Hold down "Control", or "Command" on a Mac, to select more than one.'))
            form_field.help_text = form_field.help_text.replace(repl, '').strip()
        return form_field
