[RP] text selection feature request

[Joe Corneli]

I sent a version of this to Shawn but I thought I should also put it out
there for the rest of the "ratpoisoning community".  Besides, I've thought
a little more about how I'd like the feature to work...

The request is as follows: the ability to turn the cursor into a text
selection tool. For example, if I am working with rxvt and xemacs, my
keystrokes might be something like this (I am making up the keybindings to
correspond roughly to emacs bindings without regard for what the bindings
actually do currently):

 // Note: I'm imagining that I start out in rxvt on the command line,
 // there is some text further up on the screen that I want to put into
 // a document I am editing.

escape-~         // cursor becomes hollow; I have a new "ghost" cursor...
up               // that I can move around. The hollow one stays put...
up               // on the command line. I am now two lines up the screen
escape-space     // I set the mark
up up up home    // and I select some text
escape-w         // I copy the text between the mark and the point
     
 // the hollow cursor gets filled in now, things are normal in rxvt

escape-b         // I change to xemacs, where I have a regular cursor
down down down   // that I can move around in my xemacs window
escape-y         // I insert the text into the current buffer 
escape-b         // I change back to rxvt

I could, of course, copy from xemacs to rxvt this way too... or between
any other pair of programs with editable text.  In many programs there are
different text boxes; these programs should be the ones to support getting
you around between the text boxes (though they don't always do this in the
nicest way). Once inside a text box in any program, you should be able to
kill and yank text using the feature discussed above.
