Shocking how far ahead Claude Code is from Codex on the CLI front.

Thanks for putting this together! It's really nice to have a quick reference of all the features at a glance — especially since new features are being added all the time. Saves a lot of digging through docs.

I think this is the argument for UIs - it should be self-explanatory since it's singificantly simpler than an IDE

CMD + V to paste an image is wrong.

On Mac it's the same as Windows, CTRL + V.

You use CMD + V to paste text.

I use Claude Code daily but kept forgetting commands, so I had Claude research every feature from the docs and GitHub, then generate a printable A4 landscape HTML page covering keyboard shortcuts, slash commands, workflows, skills system, memory/CLAUDE.md, MCP setup, CLI flags, and config files.

It's a single HTML file - Claude wrote it and I iterated on the layout. A daily cron job checks the changelog and updates the sheet automatically, tagging new features with a "NEW" badge.

Auto-detects Mac/Windows for the right shortcuts. Shows current Claude Code version and a dismissable changelog of recent changes at the top.

It will always be lightweight, free, no signup required: https://cc.storyfox.cz

Ctrl+P to print. Works on mobile too.

> Ctrl+P to print. Works on mobile too.

There’s something funny about this statement on a description of a key bind cheat sheet. I can’t seem to find ctrl on my phone and I think it may be cmd+p on mac.

Technically you could use a keyboard with any modern phone, so it’s not “wrong”, it’s just… extremely unlikely anyone would ever do it.

Classical coreference resolution failure.

The fact this needs to exist seems like a UX red flag.

Similar to prompting hacks to produce better results. If the machine we built for taking dumb input that will transform it into an answer needs special structuring around the input then it's not doing a good job at taking dumb input.

This. TUIs are not the correct paradigm for agentic operations. They are too constrained, and too linear.

Reminds me of Vercel's Rauch talking about his aggressive 'any UX mistake is our fault, never the user's' model for evaluating UIX. (It is/was Guillermo who says that, right?)

This should be all of Information Technology’s take. Your computers get hacked - IT’s fault. Users complain about how hard your software is or that it breaks all the time - IT’s fault.

The fact users deal with almost everything being objectively not very good if not outright bad is a testament to people adapting to bad circumstances more than anything.

Interesting set of shortcuts and slash commands.

Is something updated daily a good target to be printable?

erksa 1 hour ago||

If you align your printer and desk just right, youll have the new cheatsheet sliding onto your desk before Claude's even done updating itself.

munk-a 56 minutes ago|||

Yeah, I think it is. It's printable if you want to have a hard copy and it's up to you when to check for a new version. Since it's auto-updated (ideally) no matter when you visit the site you'll get the most up to date version as of that day. The issues (which I don't think this suffers from) would be if formatting it nice for printing made it less accurate or if updating it regularly made it worse for printing - these feel like two problems you can generally solve with one fix, they aren't opposed.

just buy a mac mini, septup an openclaw instance to track changes on this and call your printer, also order new paper when it runs out :)

ugh we were promised a brave new world and still have the same crap printers
