Step 1 − Use the option New File to create a file in Sublime Text editor.
Step 2 − Once the new file is available, you can insert the code, similar to any other text editor, and save the file in your working repository.
Step 3 − Once you save the associated file, Sublime Text editor provides a variety of options based on the type of file, for example .php for PHP scripts, .py for Python scripts and .java for Java code base.
Step 4 − As our code repository is on Python project, we will save the file as demo1.py, as shown below −
Code editors allow the users to edit the code scripts and text documents with various shortcut keys. In this chapter, let us understand through various examples about editing options of first text document in Sublime Text.
In this example, you will see how to add print statements at two locations.
Step 1 − Consider the first script of Python with the following code in it −
Step 2 − Let us suppose that, in the given script you want to mention the starting and ending points of the loop, using simple statements. You can write the print statement wherever required, however, in Sublime Text editor you can simultaneously add comments and statements in two places with a shortcut of Ctrl+cursor point for Windows or Linux, and Cmd+cursor point for Mac. Then, you can see the cursor points as mentioned below −
Step 3 − Now, you can insert the print statements at both the locations of the mentioned cursor points, as shown in the image below.
Sublime Text editor includes a feature to find the occurrences of the keywords included in the scripts. The shortcut key for finding occurrences of the keyword is Ctrl+D after highlighting the associated keyword.
If you want to search for a keyword, say print from the given code, you can use Ctrl+D or Cmd+D to get the count of occurrences of the associated keyword.
We can append comments at the end of line using the shortcut key Ctrl+Shift+L for Windows and Cmd+Shift+L for Mac operating system after selecting the code section where you actually need the comment.
There are various types of code editing and shortcut keys used in Sublime Text editor −

A user can open the keymap file or default key bindings using the option Preferences → Key Bindings.
The following example shows how to perform key bindings in Windows −
[
   { "keys": ["ctrl+shift+n"], "command": "new_window" },
   { "keys": ["ctrl+shift+w"], "command": "close_window" }
]
Sublime Text editor includes an option to define a key map. The key bindings defined in the file .sublime-keymap includes all the key value combinations.
You can include the following key binding set into this file and save them to check the execution, with the help of the code shown below −
[
   { 
      "keys": ["super+alt+;"], "command": "run_macro_file",
      "args": 
      {"file": "Packages/User/semicolon.sublime-macro"} 
   }
]
Here super is the Winkey in Windows or Linux, and a command on OSX operating system. Note that this code will run the macro that is located in Packages/User and is named semicolon.sublime-macro on pressing the Super+Alt+ keys.
In this chapter, you will learn various shortcuts keys to move and select the columns of a file in Sublime Text.
