Key bindings can be changed via the following three commands: Not exactly what the OP was asking for, but for completeness you can also toggle line number on/off via the default keybinding (as of v4.8) of Alt+N.Īlternatively you can rebind this key via the man file mentioned method: REBINDING KEYS So the contents of my ~/.nanorc file are simply: 1 set linenumbers See nanorc(5) for more information on the possible config /nano/nanorc, whichever isĮncountered first. It exists), and then the user's nanorc (if it exists), either ~/.nanorc INITIALIZATION FILE nano will read two configuration files: first the system's nanorc (if Nano -linenumbers foo.txt Via the config file(s)Īlternatively, according to the man page for nanorc, you can add set linenumbers in ~/.nanorc, $XDG_CONFIG_HOME/nano/nanorc or ~/.config/nano/nanorc. l, -l inenumbersĭisplay line numbers to the left of the text area. You can use the -l or -linenumbers flags. You can also move code elements and logical blocks up, down, left, and right.According to the man page for GNU nano 2.9.3 (also verified on version 4.8), you have two options for automatically opening with line-numbers shown and one for toggling them on/off once nano is open: Command Line Flags If no shortcuts are assigned to these actions in the currently selected keymap, you can assign your own shortcuts to the Move Line Up and Move Line Down actions in the Keymap page of the IDE settings Ctrl+Alt+S. You can move the line where the caret resides up and down using dedicated shortcuts: Ctrl+Shift+Up and Ctrl+Shift+Down. One way to delete a line is to select the whole line and press Delete or Backspace, but a slightly more efficient way is to press Ctrl+Y when the cursor is anywhere in that line. Learn more about different ways of duplicating lines and selected blocks. To duplicate the current line, press Ctrl+D. Instead of starting an empty line, you can duplicate an existing line and edit it as required. Instead, you can press Ctrl+Shift+J when your caret is anywhere in the first line this action will also make sure that the resulting line is formatted correctly.
When you need to remove an unnecessary line break and join the next line to the current one, there is no need to place the caret at the end of the line and press Delete. If a line contains a string literal, you can press Enter within the literal to split the string adding necessary syntax elements.
To add a new line above the current line, press Ctrl+Alt+Enter.
To add a new line below the current line, press Shift+Enter.
Normally you press Enter to start a new line when the caret is at the end of that line, but you can also start a new line if the caret is in the middle of a line. Actions described in this topic (except Delete current line) can be also applied to multiple lines with multiple carets.
