Move line to next section with SublimeText - sublimetext2

Question

I'm looking for a way to move a line to the "next section" with SublimeText. It could be in the "next paragraph" if it's text (see below), in the "next node" if it's XML, in the "next code block" if it's code, etc.
Currently I'm using CTRLSHIFTDOWN ARROW many times to move it to the next section, but I think SublimeText might have this feature out-of-the-box.
Example of main use case:
&section1
abcdef
ghijkl <--- if the cursor is in this line, pressing CTRL+DOWN would move this line...
sqfdsdfqsdfjq
&section2 <--- ...here! just between "&section2" and "Lorem".
Lorem ipsum dolor sit amet
&somethingelse <--- one more CTRL+DOWN would move it here

I finally managed to write a plugin for this:
# Put this file in "C:\Users\User\AppData\Roaming\Sublime Text 2\Packages\User\"
# Add this to "C:\Users\User\AppData\Roaming\Sublime Text 2\Packages\User\Default (Windows).sublime-keymap":
# { "keys": ["ctrl+up"], "command": "movesection", "args": {"direction": "up"}},
# { "keys": ["ctrl+down"], "command": "movesection", "args": {"direction": "down"}}
import sublime, sublime_plugin
import subprocess
class MovesectionCommand(sublime_plugin.TextCommand):
def run(self, edit, direction):
# select current line, save it and delete it
currentcursor = self.view.sel()[0].begin()
thisline = self.view.substr(self.view.full_line(currentcursor))
self.view.erase(edit, self.view.full_line(currentcursor))
# find the next/previous & and move there
if direction == 'down':
beg = self.view.sel()[0].begin()
end = self.view.size()
else:
beg = 0
end = self.view.sel()[0].begin()
contents = self.view.substr(sublime.Region(beg, end)) # https://stackoverflow.com/questions/20182008/sublime-text-3-api-get-all-text-from-a-file
offset = contents.find('&') if direction == 'down' else contents.rfind('&', 0, contents.rfind('&')) # down: first occurence, up: second-to-last occurence
cursors = self.view.sel()
cursors.clear()
location = sublime.Region(beg+offset, beg+offset)
cursors.add(location)
# move to the next line
(row, col) = self.view.rowcol(self.view.sel()[0].begin()) # go to the next line
self.view.run_command("goto_line", {"line": row+2})
# insert the text here
self.view.insert(edit, self.view.sel()[0].begin(), thisline)
# move to the line currently pasted (because of inserting the line usually including \n, it would go to next line, thus the following code is needed)
(row, col) = self.view.rowcol(self.view.sel()[0].begin())
self.view.run_command("goto_line", {"line": row})
