Hi Steven,
press('s') is allowed. So is press('S') - it presses shift for you and is thus
equivalent to press(SHIFT + 's'). You can write press('f', 's'). You cannot
write press('fs') because that's what enter(...) is for. If you try - or, as I
would deem more likely, happen do to it by mistake - you get the following
warning:
>>> press('fs')
ValueError: 'press' generates single keystrokes and is not intended to
be used for typing in long plain-text strings. Did you maybe mean one of the
following?
* enter("fs")
* click("fs")
* press('f', 's')
I'm not aware of CTRL + i having a connection with TAB. You cannot use it to
get a tab. We haven't decided on what to do when you press('\t'). If you want
three tabs, you can write
press(TAB, TAB, TAB)
If you want a tab, a letter and a newline, you can do
enter("""\tA
\tB
\tC
""")
The reasoning is that you are entering plain text, that is a string that you
would like to appear in the window you are typing into in the same way as you
are supplying it to `enter`.
If you want to type "Hello World!" without entering it, you call
enter("Hello World!")
Yes, I did write "call *enter* to do X *without entering*". You are hinting at
a valid ambiguity with `enter` that Chris already pointed out. I don't think
it's worse than the ambiguity of
>>> type("Hello World!")
<type 'str'>
We would need a new function for holding down keys to release them later. You
are again pointing out an imho valid ambiguity. However, you were just happily
using `press` with the understanding that it presses and releases keys, so I
hope this one isn't too bad.
As I said, I opened a new thread solely for overriding `type` in the context of
a GUI automation library:
https://groups.google.com/forum/?fromgroups=#!topic/comp.lang.python/GjZ2hAS1Wyk.
So far, 4/4 people there advised against it. If only Python hadn't defined
`type`...
