I have a long list of code similiar to the following. Is there a way to shorten this?
pallete.ActionDefault = themeInfo.ActionDefault is not null ? themeInfo.ActionDefault : pallete.ActionDefault;
This just assigns a value if it is not null. If it is null, do not assign any value.
only use ?? for null check. x = y ?? z

if (((Input.GetKeyDown(KeyCode.A)) && (Input.GetKeyDown(KeyCode.LeftShift))) || ((Input.GetKeyDown(KeyCode.RightShift)) && (Input.GetKeyDown(KeyCode.A))))
{
print("Well done! Next Key: " + "A");
}
What's Wrong with this if statement?
It looks like you have too many parentheses on the left side of the OR. Also, your parentheses are not correct on the right side. I believe you want to set it up like this.
if (Input.GetKeyDown(KeyCode.A) && (Input.GetKeyDown(KeyCode.LeftShift) || Input.GetKeyDown(KeyCode.RightShift)))
Edit: Revised because checking for A twice is redundant as pointed out by #Caius-jard.

Will the C# function Convert.ToInt32(text) convert different words to the same int? Any links or pushes in the right direction are appreciated!
P.S.
What about anagrams?
No, Convert.ToInt32(text) will just try to parse your text to an int, like:
Convert.ToInt32("032") will return 32 as int but
Convert.ToInt32("Brian") will throw an exception.
I assume that you want to have some kind of hashing, when you say "different words to the same int".
Try GetHashCode(). It will return the same value if you call it multiple times with the same value, for example:
"Brian".GetHashCode() will always return 1635321435

I've encountered sometimes code like this and I am kind of new to programming. I want to find out what's the meaning behind those objects or data type enclosed in parenthesis.
(int)
(datagridview)
(form)
If you see something like this it's called a cast. It's used to explicitly convert a data type to another data type.
double pi = 3.14159;
int my_int = (int)pi;
See this description on casting for more details.

How do I have it check my variable before allowing a click.
Example :
_StartControl.Click += new EventHandler(StartControl_Click);
I only want them to be able to do that if my variable "isValid" is equal to 1.
I'm not very good at forms.. Have always learned just console apps.
You can check the value of your isValid field inside StartControl_Click method. If the value is 1, you can allow the method to proceed, if it's not 1, you can simply return from the method before anything gets executed.
You can do it like this.
if(isValid==1)
_StartControl.Click += new EventHandler(StartControl_Click);

I want to gain a true or false answer if this variable is enable to be converted from string into a int value.
Is there a build-in syntax for it in C#?
Use int.TryParse
string numberString = "123";
int number;
bool isConvertible = int.TryParse(numberString, out number);
