Howdy!
We have introduced a new hotkey to the flow builder that makes it easier to find your flow when lost.  Pressing the f key will now snap your canvas to the uppermost left step in your flow:

While we are here, below you can find a summary of all the hotkeys currently implemented in the builder:

Step search shortcuts
