-The Main Menu of Quick Scenario Analysis with Tree provides you with a tree on the left hand side of the screen. This tree represents all of the parameters and variables used in IFs. One way to find the parameter or variable you would like to change is to understand the general groupings of these categories. The first two options on the tree, Technological Change and Environmental Uncertainties, allow you to shape the intensity of technological growth and the intensity of various environmental trends. The third, fourth and fifth option on the tree, Households/Individuals, Governments/Social-Political Systems and Firms/Businesses, allow you to shape the parameters for the three main global actors. The final two options on the tree, Selected Initial Conditions and Relationship Parameters, allow you to change parameters at the onset of your run-file or the relationships between various parameters.
+The '''Change Numerically''' table is where the changes to a parameter are made from. Use the '''Next Year''' or '''Previous Year''' buttons to change the '''Year''' field by one. Once at the desired year to start an intervention shown in the '''Year''' field, enter in the '''Desired Value''' field the value to change the parameter to, use the '''Years to Repeat or Interpolate''' field to set the number of years for the intervention to take place (this includes the current year so to increase the value for the next 10 years enter 11). Click '''Change/Repeat''' to apply the desired value for the number of years entered (for example an increase to 8 for 61 years from 2090 to 2150, shown above) or click '''Interpolate''' to smoothly shift the value over the number of years entered from the current value to the desired value. Continue to use the '''Change Numerically''' table until the parameter is adjusted as desired.
-Another way for you to find the parameters you would like to change is by selecting the "Parameter Search" option on the top right of the toolbar. Clicking on this with bring up a window with a search box. For example, if you are looking to work with the malnourished children parameters, type in "malnourished" and hit enter. This will bring up any parameter with the word "malnourished" in its name. You can also search for the parameter or variable by its abbreviation.
+To ensure that the parameter is adjusted as desired hover over the graph to see the parameter value in any given year. Click '''Register Change''' to apply this intervention to the current scenario, '''Cancel All Changes''' to clear the current parameter adjustments, '''Exit to Scenario Tree''' to return to the scenario tree, or '''Help''' to open the corresponding page in the [[Main Page|Pardee Wiki]].

Alternately, use the slider or enter the desired number into the field above the slider and click '''Apply'''. Using this slider or field option will apply that value to the whole time horizon to the year 2150, with an initial shift period based upon the choice from the '''Shift Years''' dropdown. In the example, the value is 5.177, and the shift years are 10, so the parameter interpolates from 1 to 5.177 from 2020 to 2030 and then stays at that value for the whole horizon.

	Adjust the initial parameter value to make interventions using default changes by clicking the bubble for '''High''' or '''Low''', or to return to the base click '''Base'''. Instead of using the default options use the slider or enter the desired number into the field above the slider and click '''Apply'''. Using this slider or field option will apply that value to the whole time horizon to the year 2150, with an initial shift period based upon the choice from the '''Shift Years''' dropdown. In the example the value is 5.177 and the shift years are 10, so the parameter interpolates from 1 to 5.177 from 2020 to 2030 and then stays at that value for the whole horizon.
