This document provides a brief description of the editor environment and its commonly used commands.\n\n## The editor interface\n\nOnce you have set up and started an analysis, create a notebook where you will enter your code. The editor screen showing a notebook looks like this:\n[block:image]\n{\n \"images\": [\n {\n \"image\": [\n \"https://files.readme.io/7d407f7-editor-quick-reference-1a.png\",\n \"editor-quick-reference-1a.png\",\n 1435,\n 693,\n \"#070707\"\n ]\n }\n ]\n}\n[/block]\nThe main elements of the editor are:\n1. **Notebook** - The document that contains the code and outputs of an interactive analysis, as well as additional markdown or raw text that accompanies the code, but is not meant for execution.\n\n2. **Cell** - A single section of a notebook where you can enter code, markdown or raw text.\n\n3. **Toolbar** - Allows you to quickly perform the most common actions within a notebook, by clicking on an icon:\n * <img src=\"https://files.readme.io/519377b-save.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Saves the current content of the notebook.\n * <img src=\"https://files.readme.io/2af6e1f-add.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Adds a new cell below the selected one.\n * <img src=\"https://files.readme.io/f84c5cc-cut.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Cuts the currently selected cell(s).\n * <img src=\"https://files.readme.io/64e7f6b-copy.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Copies the currently selected cell(s).\n * <img src=\"https://files.readme.io/9bcbfde-paste.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Pastes the copied cell(s).\n * <img src=\"https://files.readme.io/463bd79-run.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Executes the code in the current cell and moves to the next cell.\n * <img src=\"https://files.readme.io/6ddbef9-stop.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Stops the execution.\n * <img src=\"https://files.readme.io/a8c41ca-reload.png\" width=\"auto\" align=\"inline\" style=\"margin:1px\"/> Restarts the kernel.\n * <img src=\"https://files.readme.io/6957353-type.png\" width=\"auto\" align=\"inline\" style=\"margin:1px; border: 1px solid #000;\"/> Defines the cell type. Can be **code**, **markdown** or **raw**.\n\n4. Left-hand panel with the following tabs:\n * **Files** - Displays files that are created or added (uploaded or downloaded) within the analysis itself, including the Jupyter notebooks (**.ipynb** files). Files that are grayed out will not be saved automatically after the analysis is stopped. However, you can always choose to save a file manually, by right-clicking it and selecting **Save To Project**.\n * **Project Files** - Lists all files from the project (available under the **Files** tab in the project) in which you are executing your analysis. To use a project file in your analysis, you need to reference it in the code using its full path. Clicking a file in the list will copy the path to the clipboard, which you can then paste in your code.\n * **Running** - Displays the kernel sessions that are currently running. One kernel session corresponds to one open notebook.\n * **Commands** - Shows a list of commands that can be used within the editor, along with their keyboard shortcuts. To execute a command, click it in the list.\n5. **Terminal console** - This is a JupyterLab Terminal extension equivalent to a Linux shell.\n6. **Code console** - Enables you to run code interactively in a kernel.\n7. Analysis control buttons:\n * **Stop Analysis** - Allows you to stop the analysis directly from the editor.\n * **Go To Analysis** - Takes you to the analysis details page.\n\n## Commonly used text commands\n\nBesides execution of Python, R or Julia code, you can also run the following types of commands directly in your notebook:\n\n* **Magic commands** - a set of predefined functions that you can call with a command line style syntax. Magic commands can begin with a single `%` symbol, in which case they take the rest of the line as an argument. If you prefix a magic command with a double `%` symbol (`%%`), it will take the rest of the cell as its argument. Learn more about [magic commands](http://ipython.readthedocs.io/en/stable/interactive/magics.html) or type `%magic` in a blank cell and execute it.\n* **Linux shell commands** - You can also run any system shell command by prefixing it with an exclamation mark (`!`), for example `!ls`. You can even combine shell commands with the rest of the code in your notebook, for example:\n[block:code]\n{\n \"codes\": [\n {\n \"code\": \"myfiles = !ls\",\n \"language\": \"python\"\n }\n ]\n}\n[/block]\n This line of code will assign the list of files returned by the `ls` command to the `myfiles` variable.\n\nFind out more about functionalities related to [text commands](http://ipython.readthedocs.io/en/stable/interactive/tutorial.html).","excerpt":"","slug":"editor-quick-reference","type":"basic","title":"Editor quick reference"}
