Edit text

At its core, JetBrains Fleet is a lightweight text editor, ideal for viewing and editing individual text files. Let's take a look at some of the editor features available in JetBrains Fleet:

Split view

  • It is often helpful to work in multiple tabs side-by-side. To do this, drag a tab to the side of the editor for a vertical split, or to the top or bottom for a horizontal split.

  • You can also use the following preconfigured shortcuts:

    • Split Right: ⌘ \

    • Focus First Split: ⌃ ⇧ 1

    • Focus Last Split: ⌃ ⇧ 2

    • Focus Next Split: ⌃ ⇧ ]

    • Focus Previous Split: ⌃ ⇧ [

    To configure additional shortcuts for split actions, refer to Review and edit key bindings.

Multiple carets

You can make changes in several places at once using multiple carets. To add additional carets, do one of the following:

  • Press ⌘ ⌥ ↑ or ⌘ ⌥ ↓ to add carets above or below the current one.

  • Hold Alt+Shift and click the places where you want to add carets.

  • Position the caret on a repeated word or text fragment, then press ⌘ ⇧ L to add carets to all occurrences in the file.

With multiple carets, you can type, copy, paste, complete code, and more—just like with a single caret.

Expand and shrink selection

  • You can expand or shrink the selection at the caret based on the surrounding text or code structure.

    Use ⌥ ⇧ ↑ to expand the selection to the outer scope, or ⌥ ⇧ ↓ to shrink it to the inner scope.

Whether you want to perform a full-text search, navigate to a file or class, or simply cannot remember how to do something in JetBrains Fleet, the Go to dialog is the right tool.

  • Press ⌘ K and select the relevant tab.
