Is there a modified version of the United States QWERTY keyboard with more symbols?

I'd like to have the US QWERTY layout (so my keyboard still works,) but also have some addition symbols from other languages. It's almost like adding the Alt-Graph and it's features from the UK/Irish or Canadian French keyboard to the US QUERTY keyboard without having keys move (like @ being in a different position.) The reason I'm asking for this is sometimes having to bring up the Windows 10 character selector is a annoying when I just want a character such as the £ symbol. All I need is some software keyboard layout to make this work, I might try to experiment and see if an AutoHotKey script configured the right way might help.

The US keyboard is old before any international features were even thought of. US International Keyboard works like European keyboards for special characters using Alt Gr key.

The Dead Keys

The dead keys are the apostrophe ('), quotation mark ("), accent grave (```), tilde (~), and caret (^). If these are pressed the system waits for the next key. If it is in the list below then it enters the symbol character else it enters both keys separately. These work with uppercase where appropriate. Press Space to insert the dead character.

Alt + Character Code

Holding down alt and pressing the character code on the numeric keypad will enter that character. The keyboard language in use must support entering that character. If your keyboard supports it the code is shown on the right hand side of the status bar in Character Map else this section of the status bar is empty. The status bar us also empty for characters with well known keys, like the letters A to Z.

However there is two ways of entering codes. The point to remember here that the characters are the same for the first 127 codes. The difference is if the first number typed is a zero of not. If it is then the code will insert the character from the current character set else it will insert a character from the OEM character set. Codes over 255 enter the Unicode character and are in decimal. Characters entered are converted to OEM for Dos applications and either ANSI or Unicode depending on the Windows' application. See Converting Between Decimal and Hexadecimal.

E.G., Alt + 0 then 6 then 5 then release Alt enters the letter A.

Hex To Unicode IME

In programs based on the Rich Edit 3 control, such as Wordpad, enter a Unicode number in hexadecimal format into the document then press Alt + X. This will convert the number typed into the Unicode character. Select a character and press Alt + X to convert that character into it's Unicode number. The code is shown on the left hand side of the status bar in Character Map in the form U + <hexadecimal code>, e.g., U + 0061 for the letter a.

Selecting letters A to E will result in it being considered a hexadecimal number and it will convert to the Unicode characters (which are things like form feed and the enter key).
