A QMK keymap for the Sweep, a split keyboard with 34 keys. It makes extensive use of layers to fit all keys, and uses callum-style mods.

Features

• Custom layout optimized for French and English, Erglace (can be dynamically switched with AZERTY)
• A layer for all symbols
• A layer for navigation keys, like the arrow keys
• A tri layer for numbers and function keys
• One shot modifiers, taken from the awesome Callum's keymap
• One shot layer for French accents and useful Unicode characters, inspired by QWERTY Lafayette
• Swapper keys to emulate Alt+Tab like behaviors with one key, once again from Callum's keymap
• A layer to emulate a mouse
• Key overrides with modifiers to fit media keys and useful shortcuts
• Compilation for QWERTY or AZERTY depending on a config flag (by default, the computer should be set to French input)

Layers

Full version, with mouse layer and key overrides.

Special behaviors

Modifiers

• The one shot modifiers are on the NAV and SYM layers. When a mod is tapped, it is queued and will be applied to the next key (for exemple a letter on the base layer).
• Pressing NAV or SYM again cancels any queued modifier.
• To do the same shortcut multiple times, the modifier can be held. It stays active even if the layer changes.
• caps word is a QMK feature that enables caps lock for one word only, useful to write constants.
• Accented letters from the one shot layer can be made uppercase with shift.
• An override is defined to be able to do a quick press of the super key, achieved with super+ctrl on the NAV layer

Navigation lock

• Because it is used very often, the NAV layer can be locked by pressing shift with the thumb when on the layer.
• Alternatively, shift and then NAV does the same (if shift was not used to make a letter uppercase).
• Any layer key unlocks the layer, except for SYM if a modifier is active, to be able to navigate with super+<number> on a window manager.
• Holding shift or pressing caps word also disables the layer.

Key tri layers

• This feature is a mix between key overrides and tri layers: activating a layer AND pressing a key activates another layer. This is useful to put many shortcuts on the left split, to be used with the mouse.
• NAV+alt activates a media keys layer
• NAV+super activates a browser navigation layer
• NAV+ctrl activates a shortcuts layer
• SYM+shift activates a zoom layer

Mouse layer

• slow mouse button make the cursor speed slower for more precision.
• onesht buttons stand for 'one shot click'. The mouse layer is disabled after the button is clicked, unlike the other buttons.
• A tap on NAV, SYM or shift exits the mouse layer.
• erglce stands for Erglace, my custom layout. It can be switched with AZERTY (including the one shot special characters layer, see the keymap definition).
