Get the input in the code and use its .text value. With that value you can now get elements out of a dictionary like:

 Dictionary<string, GameObject> dictionary = new Dictionary<string, GameObject>();
 InputField input = FindObjectOfType<InputField>();
 input.text = "foo";
 GameObject elementFromDictionary = dictionary[input.text];

If you want to populate a dictionary by player defined key and value then get the values and add it like this:

 Dictionary<string, GameObject> dictionary = new Dictionary<string, GameObject>();
 
 string key = "foo"; // Get this from whatever the player enters
 GameObject foo = new GameObject(); // This is the userdefined value
 
 dictionary.Add(key, foo); // pass the key and the stuff you want to have in the dictionary

I'm sorry but this doesn't help me. I already have values and keys stored in Dictionary. What I want to know is how to put it's keys that have the user defined value into a list

Okay that clears things up:

 Dictionary<string, int> dictionary = new Dictionary<string, int>();
 dictionary.Add("foo", 10);
 dictionary.Add("bar", 20);
 dictionary.Add("baz", 10);
 
 List<string> listWithKeys = new List<string>();
 
 foreach (KeyValuePair<string, int> dictionaryItem in dictionary) {
     if (dictionaryItem.Value == 10) {
         listWithKeys.Add(dictionaryItem.Key);
     }
 }

In this case the value 10 is what the user typed into the input.
