Value Ladder

From TouchDesigner 099 Wiki

Value Ladders allow you to change the value of numerical parameters with a mouse. Hold MMB on the parameter's value field or label to open the value ladder (alternatively, hold LMB). The value ladder will pop up with .01 .1 1 10 100 options. With middle-mouse still down, move to one of the powers of 10, then drag to the right/left to increase/decrease the value.
