Set cursor blink in Grok Build

cursor_blink under [ui] forces a blinking or steady block cursor in the TUI. When the key is unset, Build inherits whatever your terminal already does. Official: Settings reference.

Values

Value	Meaning
true	Force a blinking block cursor
false	Force a steady (non-blinking) block cursor
unset	Inherit the host terminal cursor blink

Pin it in user config

[ui]
cursor_blink = false

Or force blink:

[ui]
cursor_blink = true

File path: ~/.grok/config.toml / $GROK_HOME/config.toml. UI options also live under /settings (alias /config).

Pair with prompt editing modes

Control	Effect
simple_mode	Readline-style prompt editing when true; experimental vim prompt keys when false
vim_mode / /vim-mode	Vim keys in scrollback (not the prompt) — Enable vim mode

Pitfalls

• Editing project .grok/config.toml for [ui] — user config only.
• Expecting cursor_blink to change the host terminal’s global cursor — it only affects Grok Build’s TUI cursor.
