			`: setpos ( -- ) EDPOS @ 64 /MOD`
VE: add I command Also, add insert and find buffers to the header, making it 3 lines high. Also, fix the "I" overshadowing word which wasn't operating on the proper RSP level. Also, fix I which didn't mark the block as dirty. 2020-06-05 12:54:27 +10:00			`3 + ( header ) SWAP 3 + ( gutter ) SWAP AT-XY ;`
VE: add command 'f' Kinda proud of this one. Efficiently piggy-backing on the Block Editor, keeping things simple, and yet, building power into the editor. 2020-06-07 11:46:46 +10:00			`: cmv ( n -- , char movement ) acc@ * EDPOS @ + pos! ;`
VE: Improve I and F buffer typing Previously, it would keep the old buffer displayed why typing over it. I had kept it thus because I didn't want to erase the buffer right away because the behavior is that when we type nothing, we keep the buffer as-is and repeat the action. Now, the behavior of I and F is much better. It keeps the buffer displayed until the first non-return keystroke and then erases it. Also, fixed PSP leak in _type and fixed PSP overuse in successful _F (they balanced out). 2020-06-09 11:23:23 +10:00			`: buftype ( buf ln -- )`

VE: disallow buffer overflow during typing When reaching the end of the buffer when typing in IBUF or FBUF, stop typing instead of overflowing. 2020-06-12 04:48:18 +10:00			`SWAP DUP _zbuf C!+ DUP 63 + SWAP DO`
