Inline Duct Editing
When you add a new duct segment you can edit its dimensions inline. Tab moves between fields and can switch the duct shape without touching the mouse.
| Key | Action |
|---|---|
| Tab (from Length) | Move to the size field (diameter if round, width if rectangular) |
| Tab (from Diameter) | Switch duct from round to rectangular and move to the Width field |
| Tab (from Width) | Move to the Height field |
| Enter | Confirm and close the editor |
| Escape | Cancel and discard changes |
To switch a round duct to rectangular, in the inline editor press Tab from the diameter field. The shape toggles and the cursor lands in the Width field ready to type.
Inline Tee Editing
When you add a tee, an inline editor opens ready to set the branch and main CFM values. The selected port after closing determines which leg you build next.
| Key | Action |
|---|---|
| Enter (from Branch CFM) | Confirm and close — port set to Main, ready to continue the main run |
| Tab (from Branch CFM) | Move to Main CFM field |
| Enter (from Main CFM) | Confirm and close — port set to Branch, ready to build the branch leg |
| Shift+Tab (from Main CFM) | Move back to Branch CFM field |
| Escape | Close without committing changes |
Quick tee flow: hit T, type the branch CFM, hit Enter — done. The main port is selected and you can keep building downstream. If you need to set both values, use Tab to reach Main CFM before pressing Enter.
