Getting a Form Value Programmatically

How can I read the value of a text element on a Power Apps edit form programmatically?
 
E.g. I've put a button on the form and whenever I click the button I want to read the value of whatever the user typed into a text element.
 
And then maybe after reading it, I'll want to change it and write it back. Is that possible with Power Apps?
 
Thanks!

    You could use something like 
    UpdateContext({varMessage: "Hello, World!"});
    UpdateContext({buttonPressed: true});

    in theOnSelect of a button and 

    If (
        buttonPressed,
        varMessage,
        Parent.Default
    )

    in the default of the datafield but do you want to be able write back the original value and overwrite more than once as the buttonPressed value still needs to be reset (probably on update or cancel). 

    You can read the value by using the text property of the control thus TextInput.Text

    Thanks ronaldwalcott,
     
    So here's what I did that seems to do what I need. 
     
    I create a variable for the text field and set the text field's Default property to equal that variable.
    The button's OnSelect looks like:
     
    Set(varTemp, DataCardValue14.Text);Set(varCCRecipients, Concatenate(varTemp, " says hi"));
     
    • DataCardValue14 is my text field in the edit form; its Default is varCCRecipients
    • varTemp is a temporary variable.
    I was reading DataCardValue14.Text before, but because I wasn't going through a variable to get it to another form element, it appeared that it wasn't working. 
     
    Thanks for your help.
