Don't copy/cut the current line when invoking the Copy or Cut action with no selection

This option lets you override the default behavior of copying Ctrl+C or cutting Ctrl+X the whole current line when nothing is selected in the editor.

Render special characters, such as control codes, using their Unicode name abbreviations

When this option is selected, you can use the Unicode name abbreviations for special characters, such as control codes.

Tab character rendering

You can select one of the following options:

• Horizontal line

• > symbol

• Long arrow

Left margin in distraction free mode

This option lets you adjust the left editor margin in the distraction-free and zen viewing modes.

By default, the editor text in these viewing modes is centered vertically and the text column width corresponds to the Hard wrap at option on the Editor | Code Style page of the IDE settings Ctrl+Alt+S. This means that if your code will be centered when formatted properly, but if there are long unwrapped lines, the text might go beyond the viewport while there is a large margin on the left. In such cases, you may want to decrease the left margin using this option.

Force soft wrap in documents with lines longer than ncharacters

The default number is 100000. Increasing this number might negatively affect the editor performance.

Move caret down after Comment with Line Comment action

This option lets you configure whether to move the caret to the next line if you comment a line with a line commentCtrl+/. Note that if there is a selection in the editor, the caret will not move regardless of this option.

When navigating to a file, prefer selecting existing tab in inactive split pane

When you navigate to a file that is already opened in the inactive split, use this option to activate the existing file in that split pane instead of opening a new copy of the file in the active split.

Open declaration source in the same tab

When you navigate to a method, class or variable, the source file that contains their declaration will replace the current tab if there are no changes.

Open declaration source called from a detached window in the main IDE window

When you navigate to a method, class, or variable from a detached window, RubyMine will open the source file containing the declaration in the main editor.

Perform 'Hide All Tool Windows' / 'Restore Windows' with double-click on editor tab

When this option is enabled, you can double-click editor tabs to hide and restore all tool windows. Alternatively, you can do that by pressing Ctrl+Shift+F12 or by choosing Window | Active Tool Window | Hide All Windows/Restore Windows from the main menu.

Perform 'Maximize Editor' / 'Normalize Splits' with double-click on editor tab

When this option is enabled, you can double-click tabs in split editor tab groups to change relative size of the tab group: the first double-click will extend the tab and its group to the maximum and shrink all other groups to the minimum width/height; the second double-click will allocate the same width and height for each tab group.

Alternatively, you can choose Window | Editor Tabs | Maximize Editor/Normalize Splits from the main menu or pick these actions from the Find Action popup Ctrl+Shift+A.

This option can work together with Perform 'Hide All Tool Windows' / 'Restore Windows' with double-click on editor tab, but be prepared to have multiple changes in the IDE layout every time you double-click a fie tab.

Use Safe Force Push

When this option is selected, RubyMine uses --force-with-lease when force push is called from the IDE instead of just --force.

Check for incoming and outgoing commits

When this option is selected, RubyMine updates the information on the branches that have incoming or outgoing commits in the Branches popup.

Use Windows certificate store

When this option is selected, it forces Git to use Windows certificate store to verify SSL connections. This works for Git 2.14 and later versions.
