Bermeo Layout for Corne

Features

Corne for neo-latin creatives

• Usable with left hand only (Figma, Adobe, Spline, etc) to combo with mouse.
• Delete and enter keys on the left side.
• Z and X on left side with lower layer used to control the monitor's brigtness.
• Arrow keys on left hand (vim logic)
• Accentuations used in Romance (neo-latin) languages like Spanish, Portuguese, French and Italian - ` ~ ^ ' -.

Direct ç and ã keys

The termination "tion" (eg. action) in portuguese is "ção" (eg. ação). This layout is optimized to use the less keys possible to write words with this termination.

Compared to the crkbd:default layout the difference to output ção would be half of the interations:

crkbd:bermeo	MO(2), KC_C, KC_A, MO(2)
crkbd:default	KC_QUOT, KC_C, MO(2), KC_SFT, KC_GRV, MO(2), KC_SFT, KC_A

[ _{hold key} , ^{release key} ]

Modern OLED Support

• Non-intrusive OLED layer indicator.
• Non-intrusive OLED modifier indicators ⌘ ⇧ ⌥ ⌃.
• Fully animated Luna on left side.

Full per-key RGB Matrix support

With the index of every key mapped in the table below to be used with rgb_matrix_set_color(index, r, g, b);.

Indexes of the keys

24	23	18	17	10	9			36	37	44	45	50	51
25	22	19	16	11	8			35	38	43	46	49	52
26	21	20	15	12	7			34	39	42	47	48	53
				14	13	6	33	40	41

Each layer uses the LED 14 as an visual indicator:

• ⚫️ Default layer
• 🔵 Lower (0)
• 🟠 Raise (1)
• 🟢 Numpad (2)
• ⚪️ Control and Command
• 🟡 Shift

Mod-taps

For convenience, QMK includes some Mod-Tap shortcuts to make common combinations more compact in your keymap:

Key	Description
LCTL_T(kc)	Left Control when held, kc when tapped.
LSFT_T(kc)	Left Shift when held, kc when tapped.
LALT_T(kc)	Left Alt when held, kc when tapped.
ALT(kc)	Left Alt + kc when tapped.
LGUI_T(kc)	Left GUI when held, kc when tapped.
RSFT_T(kc)	Right Shift when held, kc when tapped.
RGUI_T(kc)	Right GUI when held, kc when tapped.

Macros

Layer	Name	Description	Keys
🟠	CEDILLA	Directly outputs ç	' + c
🟠	AO	Directly outputs ã	shift + ` + a
🟠	ASPAS	Outputs ", since diaeresis1 are less used than " (for coding and quoting)	shift + ' + space

1. The diaeresis (/daɪˈɛrəsɪs, -ˈɪər-/ dy-ERR-ə-sis, -⁠EER-; also known as the trema) and the umlaut (/ˈʊmlaʊt/) are two different diacritical marks that (in modern usage) look alike. They both consist of two dots ¨ placed over a letter, usually a vowel; when that letter is an i or a j, the diacritic replaces the tittle: ï. In computer systems, both forms have the same code point (binary code). Their appearance in print or on screen may vary between typefaces but rarely within the same typeface. The "diaeresis" diacritic is used to mark the separation of two distinct vowels in adjacent syllables when an instance of diaeresis (or hiatus) occurs, so as to distinguish from a digraph or diphthong. The "umlaut" diacritic, in contrast, indicates a sound shift phenomenon – also known as umlaut – in which a back vowel becomes a front vowel. Neither of these phenomena occur in English, except in loanwords (like naïve) or for stylistic reasons (as in the Brontë family or Mötley Crüe). ↩︎
