Sublime Text on OS X, make Cmd+F do the equivalent of Cmd+E followed by Cmd+F. Works for all selections, not just single line like "find_selected_text" setting.

run_multiple_commands.py

import sublime, sublime_plugin

# Takes an array of commands (same as those you'd provide to a key binding) with
# an optional condition, context (defaults to view commands) & runs each command in order.
# Valid condition is 'selected_text'.
# Valid contexts are 'text', 'window', and 'app' for running a TextCommand,
# WindowCommands, or ApplicationCommand respectively.
class RunMultipleCommandsCommand(sublime_plugin.TextCommand):
	def exec_command(self, command):
		if not 'command' in command:
			raise Exception('No command name provided.')

		# Check that the condition for this command is met.
		if 'condition' in command:
			condition = command['condition']
			if condition == 'selected_text':
				selected_text = False
				for r in self.view.sel():
					if not r.empty():
						selected_text = True
				if selected_text == False:
					return

		args = None
		if 'args' in command:
			args = command['args']

		# default context is the view since it's easiest to get the other contexts
		# from the view
		context = self.view
		if 'context' in command:
			context_name = command['context']
			if context_name == 'window':
				context = context.window()
			elif context_name == 'app':
				context = sublime
			elif context_name == 'text':
				pass
			else:
				raise Exception('Invalid command context "'+context_name+'".')

		# skip args if not needed
		if args is None:
			context.run_command(command['command'])
		else:
			context.run_command(command['command'], args)

	def run(self, edit, commands = None):
		if commands is None:
			return # not an error
		for command in commands:
			self.exec_command(command)

I had to add a "selected_text" condition because slurp should not run if there's no text selection.
