First version of text transfer has been added in the *default* branch just now
F2, s - sends current selection for evaluation to the REPL
Shift+F2, s - writes current selection the the REPL's panel, but does not send it just yet, you have to manually press enter at the end of the input (maybe after changing some things)
Additional shortcuts:
[Shift+]F2, f - sends/writes a whole file
[Shift+]F2, l - sends/writes all lines that are touched by any selection
If you wish to do something yourself, window commands: repl_view_write, repl_send are the place to go.
Known problem:
* sending a whole python class works if, and only if there are no empty lines in it.
