I found a soulution here: http://www.sublimetext.com/forum/viewtopic.php?f=4&t=4958

You can modify the package

trim_trailing_white_space.py

located in the default packages directory, this way:

import sublime, sublime_plugin

def trim_trailing_white_space(view):
    trailing_white_space = view.find_all("[\t ]+$")
    trailing_white_space.reverse()
    edit = view.begin_edit()
    for r in trailing_white_space:
        view.erase(edit, r)
    view.end_edit(edit)

class TrimTrailingWhiteSpaceCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        trim_trailing_white_space(self.view)

class TrimTrailingWhiteSpace(sublime_plugin.EventListener):
    def on_pre_save(self, view):
        if view.settings().get("trim_trailing_white_space_on_save") == True:
            trim_trailing_white_space(view)

class EnsureNewlineAtEof(sublime_plugin.EventListener):
    def on_pre_save(self, view):
        if view.settings().get("ensure_newline_at_eof_on_save") == True:
            if view.size() > 0 and view.substr(view.size() - 1) != '\n':
                edit = view.begin_edit()
                view.insert(edit, view.size(), "\n")
                view.end_edit(edit)

Now you can add the command to your keymap configuration:

{ "keys": ["your_shortcut"], "command": "trim_trailing_white_space" }
