How to add "new line" keyboard shortcuts in spyder

When using other editors, most of them have a function about "new line". For example, the Sublime Text, use
Ctrl + enter
to enter new line directly whatever cursor is at end of line or not. After checked all the setting about spyder, have no idea about this.
Thus i want to add new feature about "new line" with
Ctrl + enter
To enter a new line without the cursor need to move to tail
Would you have some ideas to share me ? Thank you.
I'm just a Spyder user, but yes you can add such a functionality yourself. For this you need to modify the file
codeeditor.py, which in Windows is under
WARNING: Backup the codeeditor.py file before modifying it.
What you need to do is to modify the
keyPressEvent function that starts at line 2129 (in my Spyder 2.3.1).
You'll see that one of the first conditionals takes care of enter/return keypresses: line 2139,
if key in (Qt.Key_Enter, Qt.Key_Return):
ctrl+Enter is already taken... so without messing too much with the options, I'm just going to put here an option for
ctrl+shift+Enter, which is free to use. Is this ok?
So what you want to do is to add, after the option
if not shift and not ctrl:, another option with shift and control pressed; i.e. in my case I would add this at line 2153, with indentation to match the
if not shift and not ctrl: line:
elif shift and ctrl: # Insert newline functionality cursor = self.textCursor() startpos = cursor.position() # Remember where the cursor is self.stdkey_end(False, False) # Go to the end of the line self.insert_text(self.get_line_separator()) # Add a newline cursor.setPosition(startpos) # Go back to the initial position self.setTextCursor(cursor)
Now close Spyder, and reopen it. Try the
enter combination in the editor, and you should get a new line just below the line you're in, as you wanted.
If you don't mind rebinding or eliminating the "Run cell" functionality in your own copy of Spyder, you could even play around and put this code under the
elif ctrl: condition, then you'd have the
enter binding just like in Sublime Text.
Addition, Use a number line if you're just learning to add. Draw a line, then write numbers along the line from 0-15. Circle the first number you want to add. Start at that number. Then, count down your number line, moving the same number of spaces as the second number you're adding. Adding integers is similar to adding whole numbers, but integers can be positive or negative. To add two negetive integers, you add the same way as you would add whole numbers, but place a negative sign in front of the answer. Adding positive and negative integers can get more tricky. To do that, you subtract the larger number from the ,smaller
If you want to continue writing in the new line (move the cursor there) instead of only adding a new line and keep the cursor where it is, just ignore the related lines in the accepted answer:
elif shift and ctrl: # Insert newline functionality cursor = self.textCursor() # startpos = cursor.position() # optional self.stdkey_end(False, False) # Go to the end of the line self.insert_text(self.get_line_separenter code hereator()) # Add a newline # cursor.setPosition(startpos) # optional # self.setTextCursor(cursor) # optional
I'am going to do a pull request on this, since I guess many others can profit from this keybinding as well. Thanks for your answer.

- Can you explain a bit more what you want this feature to do? How is it different than just pressing "enter"?
- @Blckknght Thank you,modified
- @VicYu Would you accept an option for
enter? It's because
enteris already used for "Run cell". You could rebind it in your own copy of Spyder anyways, I'm just putting here an answer that doesn't mess too much with Spyder's functionality as it is.
- @Roberto Thank you ,excellent!You're a genius!Key is fine,importance is the feature.
- Yeah ,these are something different between 2.3.1 and 2.3.2.But your post is so clear and easy-understand.I implemented this feature with your genius ,Thank you .
- (Spyder dev here) Beware that your changes to
codeeditor.pywill be erased every time you update Spyder. If you want to this functionality as part of Spyder, please open an issue in our issue tracker so we can add this code directly to our own.
