There is not an API (supported) method of doing what you are interested in. Though it seems useful, and perhaps their should be. If you can keep up with changes that may break your application, you can hack together a solution with something like the following. 1) Open http://openlayers.org/dev/examples/modify-feature.html 2) Click on the "draw line" radio to activate the draw feature control 3) Run the following in the Firebug console: var evt = {xy: new OpenLayers.Pixel(100, 100)}; controls.line.handler.mousedown(evt); controls.line.handler.mouseup(evt); In your application, you would substitute 100, 100 with the real pixel location of your click. And you'd have to have a reference to the draw feature control to get to its handler. This basically mocks up the mousedown, mouseup sequence that draws the first point. Again, this is not part of the control or handler API - you should not expect it always to work from now until the end of OpenLayers 2.x - we may change any non-API stuff at our leisure.
