How about:
put: func [str] [
if my-area <> system/view/focal-face [return]
if not system/view/caret [return]
system/view/caret: insert system/view/caret str
show my-area
]

You'd better change your Area's feel; it handles keys this way:
engage: func [face act event][
switch act [
down [
either not-equal? face view*/focal-face [
focus face
view*/caret: offset-to-caret face event/offset
] [
view*/highlight-start:
view*/highlight-end: none
view*/caret: offset-to-caret face event/offset
]
show face
]
over [
if not-equal? view*/caret offset-to-caret face event/offset [
if not view*/highlight-start [view*/highlight-start: view*/caret]
view*/highlight-end: view*/caret: offset-to-caret face event/offset
show face
]
]
key [edit-text face event get in face 'action]
]
]
i.e. calling the EDIT-TEXT function that you can find in the
CTX-TEXT object:
>> probe get in ctx-text 'edit-text
func [
face event action

if action/y - liney <= 0 [face/para/scroll/y: tmp2/y + action/y - liney]
show face
]
]
Notice the lines with:
face/dirty?: true
But I still think it would be easier to remove or change the event
func instead of having to patch edit-text...

Gabriele.
