In short this app doesn't work as intended yet. It's meant to be a keyboard with the customizability and flexibility of text editors like Sublime Text or VS Code. I started it with the desire to have cut copy and paste buttons right there on the main keyboard page.

To use it click "Enable" then turn it on in that screen then "Select" and choose it from that popup.

Here are my favorite features so far:
• Unicode table with recents
• International Phonetic Alphabet keyboard with sounds from Wikipedia
• Eight macro buttons for whatever you want date and time insertion plus buttons for your name phone number email etc (configure in settings)
• Clipboard history page (most recent 16 entries)
• Shortcuts for joining lines duplicating lines and more in any app
• Comment toggling and indentation
• Type with bold and italic text (and others) in any app
• Change selected text between camel and snake cases swap out hyphens/underscores/spaces/tabs

It has a ton of issues but here are the most salient:
• Spellcheck doesn't work on Samsung phones
• If keys are hidden by customization menu causes crash on pressing shift key
• Can't type into find/replace menu and even if it could don't know how to send text back to the editor
• Themes and specification of colors almost certainly don't work yet
• If long press popups are a certain length it hides the close button and displays incorrectly
