EKL Knowledgeware EKLQuickTips 

Some EKL action may need literal input arguments (String, Integer,...)

It is possible to tick an aption that allow to consider these literal inputs as parameters, and so to input mannually the argument value. This, in order not to have to use "Parameters" input that you would have to select in the tree.

This option is available in the "Properties" panel of the action, and so belong to it (not a general preferences). Once ticked, a small array will appear allowing the user to set default value for the literal inputs.

Once ticked, a button "Parameters" will appear the the input selection panel, allowing the user to fill its literal inputs.
