Sinhala Addendum Keyboard Layout

This is a custom keyboard layout for the Sinhalese script that aims to be easy to use for anyone with a QWERTY keyboard. The main goals of this layout are,

• To provide an layout that would be easy to transition for anyone used to typing Singlish (Not to be Confused with Singlish of Singapore)
• To be trivial to figure out/use the layout without needing the Sinhala characters printed on keys
• ...and to give myself something as half as decent as sl-sayura-m17n-db on windows

Layout Details

• All aspirated consonats can be accessed by pressing SHIFT alongside the key corresponding to the non-aspirated consonant, except for four consonants
  • The exceptions are the aspirated versions of ට, ත, ද, ඩ. For those letters you instead have to hit AltGr (Ctrl+Alt) and the corresponding key to access the aspirated version. (Reasons why will be explained bellow)
  • ALTERNATIVELY You can access any aspirated consonant utilising dead keys, Entering SHIFT+X and any valid consonant afterwards will allow you to type the aspirated consonant
• Accessing pre-nasalised letters (sannyaka akuru, ardha-anu-nasikya akshara) depends on the letter, Refer to the above layout preview to see where to access each letter
  • ALTERNATIVELY You can access any pre-nasalised consonant with dead keys, Entering the x key and any valid consonant afterwards will allow you to access its pre-nasalised form
• Refer to the above layout preview for vowel letters, every vowel letter requires the altGr key or alternatively, the use of the dead key ` alongside the corresponding vowel marker (For example ැ -> ඇ, Although for අ and ආ pleaase refer to the dead key table) to be inputted
• Ligatures such as ක්‍ය (yanshaya) and ක්‍ර (rakaraanshaya) can be accessed with SHIFT+Y and SHIFT+R respectively. For any other godforsaken ancient ligature, Please manually type them. This layout allows you to type a unicode Zero Width Joiner with altGr + shift + ,. Refer to Wikipedia Consonant Conjuncts List to know which letters are needed for the the ligature
• Some keys are repeated in the layout for ease of use and/or preference, or perhaps to attain a fake sense of consistency with some letters
• All characters which are still part of modern usage be accessed without the altGr key

Layout screenshots are terrible I know, I don't know any better way to preview it
