Add context to shortcut window's texts
src/help-overlay.ui has some strings that are also found in other parts of the UI, and they are extracted and made available for translation as an ambiguated single string. For instance:
#: src/editor-page.c:786 src/help-overlay.ui:79
msgid "Save As"
msgstr ""
Strings from shortcut window and from other places of the UI can have different translations, so please consider adding a message context (a.k.a. msgctxt) to disambiguate shortcut window's strings from the rest by adding context="shortcut window"
next to the translatable="yes"
flag in src/help-overlay.ui
Note that other GNOME software use this very same context, reason why I suggested it.
