Capital lowercase and spaces

Hello. Thanks for such good software.
“all caps hello” = HELLO

Is there a command to type a word all lowercase letters?
for example “all lower hello”?

Is there a command to type ‘hello’ after ‘and’ (When ‘and’ is already typed) without a space before hello?
for example The result would be not ‘and hello’ but ‘andhello’


‘andhello’ is achieved by saying “no space hello” (with the insertion point after “and”)

As for the “all lowercase” – sometimes, you can “select” the word, and a choice may be the lowercase version.
