@ - Inserts a newline. This only takes effect when the "maxheight"
value of 'statuslineopt' is greater than 1, or for |tabpanel|.
+ *stl-%[FuncName]*
+ %[ defines clickable regions in the statusline. When the user clicks
+ on a region with the mouse, the specified function is called.
+
+ %[FuncName] Start of a clickable region. "FuncName" is the name
+ of a Vim function to call when the region is clicked.
+ %[] End of the clickable region. If omitted, the region
+ extends to the end of the statusline or to the start
+ of the next clickable region.
+
+ A {minwid} value can be used to pass an identifier to the callback:
+ %3[FuncName] Starts a clickable region with minwid 3.
+
+ The function receives a single |Dictionary| argument with these
+ entries:
+ "minwid" The minwid value from %N[Func] (0 if not specified).
+ "nclicks" Number of clicks: 1, 2, or 3.
+ "button" Mouse button: "l" (left), "m" (middle), "r" (right).
+ "mods" Modifier keys: combination of "s" (shift), "c" (ctrl),
+ "a" (alt). Empty string if no modifiers.
+ "winid" |window-ID| of the window whose statusline was clicked.
+
+ If the function returns non-zero, the statusline is redrawn.
+ Dragging the statusline to resize the window still works even when
+ click handlers are defined.
+
+ Example: >
+ func! ClickFile(info)
+ if a:info.button ==# 'l' && a:info.nclicks == 2
+ browse edit
+ endif
+ return 0
+ endfunc
+ set statusline=%[ClickFile]%f%[]\ %l:%c
+< This makes the filename in the statusline clickable. Double-clicking
+ it opens the file browser.
+
+ Use `has('statusline_click')` to check if this feature is available.
+ This is useful for backward compatibility: >
+ if has('statusline_click')
+ set statusline=%[ClickFile]%f%[]\ %l:%c
+ else
+ set statusline=%f\ %l:%c
+ endif
+<
When displaying a flag, Vim removes the leading comma, if any, when
that flag comes right after plaintext. This will make a nice display
when flags are used like in the examples below.

+ *stl-%[FuncName]*
+ %[ defines clickable regions in the statusline. When the user clicks
+ on a region with the mouse, the specified function is called.
+
+ %[FuncName] Start of a clickable region. "FuncName" is the name
+ of a Vim function to call when the region is clicked.
+ %[] End of the clickable region. If omitted, the region
+ extends to the end of the statusline or to the start
+ of the next clickable region.
+
+ A {minwid} value can be used to pass an identifier to the callback:
+ %3[FuncName] Starts a clickable region with minwid 3.
+
+ The function receives a single |Dictionary| argument with these
+ entries:
+ "minwid" The minwid value from %N[Func] (0 if not specified).
+ "nclicks" Number of clicks: 1, 2, or 3.
+ "button" Mouse button: "l" (left), "m" (middle), "r" (right).
+ "mods" Modifier keys: combination of "s" (shift), "c" (ctrl),
+ "a" (alt). Empty string if no modifiers.
+ "winid" |window-ID| of the window whose statusline was clicked.
+
+ If the function returns non-zero, the statusline is redrawn.
+ Dragging the statusline to resize the window still works even when
+ click handlers are defined.

+ func! ClickFile(info)
+ if a:info.button ==# 'l' && a:info.nclicks == 2
+ browse edit

+
+ Use `has('statusline_click')` to check if this feature is available.
+ This is useful for backward compatibility: >

that flag comes right after plaintext. This will make a nice display
