Hello,
While in edit mode in a Markdown document Find doesn't open. I've tried both the keyboard shortcut (Ctrl+F) and adding the button to the toolbar. If I switch to browse mode Find immediately comes up and I can search. Unfortunately, when using find in a document it is more useful to search for the word then edit there, instead of using Find in browse mode then manually scrolling down the document in edit mode.
