Editing designs and user interface tips

Pots

Pots look pretty and work much of the time, but sometimes can make it hard to set a specific value. We have two tricks to overcome this:

Click on the value above the pot and type the value you want
While adjusting the pot value you can get finer precision by holding CTRL (1/100) or SHIFT (1/10)

Changing a control from potentiometer to input (and back)

To change the pot to input, right-click on the pot and select “Show as input”.

To change an input to pot, right click on the port and select “Show as pot”.

NOTE Only control ports (as defined by the component at design time) can be switched to pot / input.

Keyboard and mouse

While the app should behave in an expected way, some functions may not be obvious so these are summarised below.

Action	Keyboard	Mouse	Description
Pot value change	Shift	Left mouse button + drag on the pot	Fine value adjust - 1/10
Pot value change	CTRL	Left mouse button + drag on the pot	Fine value adjust - 1/100
Select		Left mouse button + drag on the workspace area	This selects items from the design. Selection is fairly promiscuous and inclusive on purpose - so it’s easy to select wires/connections.
Select	Shift	Left mouse button click	This adds the clicked item to selection.
Move selection		Left mouse button + drag on a selected symbol	This moves current selection or the symbol itself if nothing else is selected.
Pan		Right mouse button + drag on the workspace area	This pans the design, following the mouse
Scroll		Mouse wheel	This scrolls the design up or down
Scroll	Shift	Mouse wheel	This scrolls the design left and right
Zoom	CRTL	Mouse wheel	This zooms the design in and out
Scroll/Zoom		Laptop touchpad / multitouch	This should work normally as these translate to mouse actions.
Context menus		Right mouse button click	Opens context menus on symbols and pots.
Cut	CRTL-X		Standard copy keyboard shortcut
Copy	CRTL-C		Standard copy keyboard shortcut
Paste	CRTL-V		Standard copy keyboard shortcut
Delete	Delete key		Standard delete

Note also that menus list keyboard shortcuts where available.

Renaming a component

In a large design, especially on the “edges of the design” when exporting a graph, it is necessary to assign names to components so their ports can be easily identified.

Component rename

The environment automatically assigns component names. This is the number to the right of the component type name.

To change a name of the component, click on it and type a friendly name. Mind that there is little space so short names are best. It usually only makes sense to change the names for edge components.

Disconnecting wires

Select the wire (easiest is to drag selection until it intersects the wire) and hit delete.
