First occurence of chosen letter is used rather than clicked

[SSoelvsten]

Since the on-click command just runs the type command, then we have some unexpected behaviour when having multiple occurences of the same letter.

Consider the following situation

_ _ _ _ _ _
L E I K P E

If the last E is clicked the following is expected to happen

E _ _ _ _ _
L E I K P _

But, what actually happens is

E _ _ _ _ _
L _ I K P E
