By the way, where is this set of strings located in the software?
Is it necessary to keep the prefix space?

Thanks for the PR @TakWolf going to merge it.

By the way, where is this set of strings located in the software?

It's the command name of some special shortcuts (F4 is a historical shortcut from the Allegro Sprite Editor):

The code is here:

aseprite/src/app/commands/cmd_palette_editor.cpp

Lines 91 to 107 in 516a927

	std::string PaletteEditorCommand::onGetFriendlyName() const
	{
	std::string edit, plus, popup;
	if (m_edit) {
	edit = Strings::commands_PaletteEditor_Edit();
	}
	if (m_edit && m_popup) {
	plus = Strings::commands_PaletteEditor_And();
	}
	if (m_popup) {
	if (m_background)
	popup = Strings::commands_PaletteEditor_BgPopup();
	else
	popup = Strings::commands_PaletteEditor_FgPopup();
	}
	return fmt::format(getBaseFriendlyName(), edit, plus, popup);
	}

Is it necessary to keep the prefix space?

Yes, but only because it's a little weird how we are building the final PaletteEditorCommand string (probably difficult to replicate on other languages).

I got it. Can it be changed to:

PaletteEditor = Switch {0} {1} {2}
PaletteEditor_Edit = Edit Palette Mode
PaletteEditor_And = and
PaletteEditor_FgPopup = Foreground Color Popup
PaletteEditor_BgPopup = Background Color Popup

Right now it's not possible, as some whitespaces might be duplicated in the final result. Anyway we could post-process the result replacing " " with " " and trimming trailing spaces. I can made the change as this might simplify all translations.

I've made the change 👍
