A user has requested a tool to alter the case of text that has been typed. Marking as lowest priority, since we've made clear it's not something anyone is likely to work on any time soon.
T55210: VisualEditor: Changing the first letter of wikilinked words is difficult
T52678: VisualEditor: Pre-annotation is from up-page, so deleting and replacing the first character in a link de-links it; deleting and replacing the first bold character in a word de-bolds it; etc.
T55495: VisualEditor: Link insertion dialog should preserve the case of the initial character
T52452: VisualEditor: When inserting a new link (not annotating on existing text), the suggested link is capitalised even if your input text isn't, so leading to unexpected capitalisation of link anchors
