    copied!<p>Edit: Turns out, I was misled during my initial explorations of the accessibility APIs. Once I found the secure text field in the AX hierarchy, I was easily able to set the value. Not sure what to do with this question beyond that, but I wanted to update this for future searchers.</p> <p>I'm working on some code that will post keyboard events to targeted applications using the Accessibility APIs. So far, I have been able to write a trivial app that allows me to type in a string value and then post keyboard events with those key codes to the targeted application. In reality, the strings would be read from another location.</p> <p>What I have not yet been able to figure out is how to ascertain whether and which modifier keys should also be posted. For instance, when I type <code>Hello, world!</code> into my test application, the input is sent to the other application as <code>hello, world1</code> because I am not yet including the modifier keys to create the upper case H and the exclamation point. This is made doubly complicated by multi-keystroke characters like <code>é</code> or <code>ü</code>. Sending <code>é</code> sends a raw <code>e</code> with no accent for example.</p> <p>Is there a simple method I am overlooking for discerning the modifiers to combine with a keycode for creating a particular NSString or unichar? If not, does anyone have a suggestion of how to proceed? So far, the best I have come up with is calling <code>UCKeyTranslate</code> with all possible modifier combinations until I find one that matches the <code>unichar</code> I get using <code>-[NSString characterAtIndex:]</code> I'm not sure this is scalable or reliable, though, given the multi-keystroke nature of some characters as noted above.</p> <p>Thanks in advance!</p>
