Upcase-region, downcase-region. Or create something own.

you might be interested in this function:
(defun toggle-letter-case ()
"Toggle the letter case of current word or text selection.
Toggles from 3 cases: UPPER CASE, lower case, Title Case,
in that cyclic order."
(interactive)
(let (pos1 pos2 (deactivate-mark nil) (case-fold-search nil))
(if (and transient-mark-mode mark-active)
(setq pos1 (region-beginning)
pos2 (region-end))
(setq pos1 (car (bounds-of-thing-at-point 'word))
pos2 (cdr (bounds-of-thing-at-point 'word))))
(when (not (eq last-command this-command))
(save-excursion
(goto-char pos1)
(cond
((looking-at "[[:lower:]][[:lower:]]") (put this-command 'state
"all lower"))
((looking-at "[[:upper:]][[:upper:]]") (put this-command 'state
"all caps") )
((looking-at "[[:upper:]][[:lower:]]") (put this-command 'state
"init caps") )
(t (put this-command 'state "all lower") )
)
)
)
(cond
((string= "all lower" (get this-command 'state))
(upcase-initials-region pos1 pos2) (put this-command 'state "init
caps"))
((string= "init caps" (get this-command 'state))
(upcase-region pos1 pos2) (put this-command 'state "all caps"))
((string= "all caps" (get this-command 'state))
(downcase-region pos1 pos2) (put this-command 'state "all lower"))
)
)
)
You can assign it a keyboard shortcut so you can reduce the need for
Alt+u, Alt+l, Alt+c, Ctrl+x Ctrl+u, Ctrl+x Ctrl+l to just one.

I wrote toggle-case.el to do that. You can find it here:

Let me know if you have problems.

Right! This and downcase-word (M-l) work also for the rest of the
word – and Both Will Fail On A Word That Has A Few Upper-Case Letters
In It.

Right, that is annoying. How about something like
(defun upcase-char (arg)
(interactive "P")
(upcase-region
(point)
(+ (point) arg)))

Yes, something simple like this, or a keyboard macro of his own, was
part of my recommendation to Anand. (For me it happens so rarely that
I can do this manually, once needed. With a keyboard of six or seven
modifiers an unused key binding could be determined, s-~, for example)

You could mark the letter/region and us upcase-region
