As Coda gets more and more powerful, it can be hard to remember what all the features are and where to find each one. We are working on building a centralized way for you to discover all the things you can add to your doc and insert them quickly.
A lot of modern products now rely on slash commands, where you can type / to see a full list of objects you can insert. You can also start typing to search for an object and add it quickly without leaving the keyboard at all.
We have an early version of this feature ready for you all to start testing. Please keep in mind that this version may change significantly before we launch it.
If you are interested in trying this feature and sharing your feedback, please respond below and I will reach out with instructions.
